Despite its successes in describing known macroscopic gravitational phenomena, Einsteins general relativity (GR) still lacks the status of a fundamental microscopic theory, because it admits singular solutions under very general assumptions, and all attempts to quantize GR encounter serious difficulties. In order to overcome this unsatisfying situation, one is naturally led to consider alternative approaches to gravity: gauge theories of gravity, the string theory, and noncomutative theories. The project includes two subjects:
A. Torsion and non-metricity in gravity and string/brane theory
B. Non-commutative field theory and geometry.
We expect from our research to clarify the dynamical and symmetry aspects of gravity closely related to its quantum nature. This program is realized by studying alternative gravitational theories.

Physics of nanostructured oxide materials and strongly correlated systems


Institution: Institut za Fiziku
Contractor: Ministry of Science and Environmental Protection
Contract type: National Research Project
Status: New
Begin: 31.12.2010. End: 30.12.2014.
Leadership: Dr. Zorana Dohčević-Mitrović
Contrnote:
Project consists of two sub-projects: physics of strongly correlated electron systems and physics of nano-oxide magnetic materials. In the framework of the first subproject we will investigate the spin, charge and energy transport in inhomogeneous systems with strong correlations(superconductors, spintronic and thermoelectric materials) using detailed physical characterization methods (X-ray diffraction, inelastic light scattering, absorption and photoluminescence, ellipsometry or electron-microprobe investigations, transport and magnetic measurements). We will tune intrinsic anisotropic properties and we will perform theoretical modeling based on experimental results.
In the framework of the second subproject the sol-gel and chemistry methods will be further developed and optimized for production of oxide nanomaterials based on TiO2, CeO2, ZnO and their derivatives doped with transition or rare earth elements. The proper characterization of these materials will be performed by the same set of advanced experimental techniques. Multiscale computer modeling will be used to investigate molecular transport through nanoporous media, whereas density functional theory will be performed in order to follow the changes of the electronic band structure of oxide-based nanomaterials with doping. We expect to develop controlled production processes in which nanostructure and nanomaterials with desired properties will be created for environmental and spintronic applications.

The negative effects of small particles PM10 (less than 10 micrometers in diameter (WHO, 1999)) on human health have been confirmed in numerous long-term studies on air quality in urban areas. According to the Directive of the European Commission (1999/30/EC), the UE countries are instructed to monitor PM particles and to reduce their emission in urban areas. The research activities on concentration, transport and interaction of suspended particles PM10 and PM2.5, heavy metals, natural and man made radionuclides and ozone in various medias (air, total atmospheric deposition, plant material-leaves, moss and soil) are performed at representative sampling points. Active biomonitoring method with moss bags will be used to estimate the deposition of heavy metals and radionuclides in the urban air.

Nuclear Spectroscopy and Rare Nuclear Processes


Institution: Faculty of Sciences, Novi Sad
Contractor: Ministry of Science of the Republic of Serbia
Contract type: National Research Project
Status: New
Begin: 01.01.2006. End: 31.12.2010.
Leadership: Dr. Ištvan Bikit
Contrnote:
The investigations of rare nuclear decays and low probability interactions of radiation with matter contributed in the last decade significantly to the development of "new" physics beyond the standard model of fundamental interactions. Most of the advances in the field of "non-accelerator" nuclear physics and astroparticle physics depend on background reduction and background recognition. When compared with the cross sections of weak interactions the probabilities of many higher order electromagnetic and "forbidden" strong interactions and decays become significant. Such processes creating background at the search for predicted particles are studied within the project activities. These measurements will test and support the Monte Carlo simulations of the background. Also contribution to the methodologies of low-level counting (radio purity of materials, electronic background reduction, detector calibration, counting statistics) and their application is expected.

Nanostructured multifunctional materials and nanocomposites


Institution: Institut za Fiziku
Contractor: Center for Solid State Physics and New Materials
Contract type: National Research Project
Status: New
Begin: 31.12.2010. End: 30.12.2014.
Leadership: Dr. Zoran Popović
Contrnote:
This project consists of several topics: 1. Photoluminescence and Raman spectroscopy of semiconducting nanostructures, 2. Transport properties of materials with colossal magnetoresistance effect, 3. Investigations of new superconductors in Mg-B and Cu-Pb-Ag-O systems, 4. Vibrational and magnetic properties of low-dimensional magnetic structures in spin-ladder vanadates, 5. Vibrational properties of nanotubes, small fullerens and anilin based oligomers and polymers, 6. Properties of nanocomposites obtained by sol-gel technology, 7. Quantum-mechanical engineering of semiconducting quantum structures and 8. Properties of materials under high pressure.

The investigation of single quantum dots by low-temperature micro-photoluminescence and micro-Raman is proposed, allowing direct observation of ultra narrow photoluminescence from delta-function energy levels within the dots. Low-temperature micro-Raman and micro-photoluminescence measurements will be used to investigate porous-Si made by photochemical etching of bulk material.

We will use optical methods and transport properties measurements to analyze how structural disorder influences the electronic properties of mixed valence manganites. Two different types of disorder has been considered: 1. cationic vacancies at B(Mn) sites, in the series of compounds La1-xAxMnO3+d (A=Na, K), 2. A-cations with different ionic radii in the series of compounds La0.85(Na1-xKx)0.15MnO3.

We will investigate transport and optical properties of the new high-temperature superconductor, MgB2 and search for the relevant high-temperature phase of Cu-Pb-Ag-O systems, that promises the room temperature superconductivity.

One of the central issues in the physics of strongly correlated electron systems is study of low dimensional magnetic properties. These properties, like for example the ground state energy and excitation spectra, are dominated by strong quantum fluctuation, pronounced spin-spin correlations and a suppression of the long-range magnetic order. The main goal of the present project is to identify the spin-gap related modes and relevant exchange integrals (magnetic crystal structure).in the Raman spectra of spin-ladder materials (Sr-Cu-O cuprates and AV2O5 vanadates, A=Na, Li, Cs, Ca, Mg),

Vibrational properties of nanotubes, fulerenes smaller than C60 and conducting polymers will be calculated using a model based on adiabatic harmonic approximation and valence-optical theory.

Synthesis of thin and thick films and nanocomposites in mesoporous silica-gels will be the main goal of this activity. Obtained materials will be characterized by measuring of their mechanical (density, porosity, specific surface) and optical (vibrational spectroscopies) properties.

This activity includes development of more sophistical models for semiconducting devices, such as lasers, detectors and modulators, based on intraband electronic transitions.

Optical properties of molecular crystals, such as SnGeS3, AV2O5, will be investigated at high hydrostatic pressures. We will search for phase transitions and pressure induced change of phonon dynamics in these materials.

Begin: 01.01.2006. End: 31.12.2010.
Leadership: Dr. Zoran Petrović
Contrnote:
Strategic goal of the project is to pursue studies of fundamental processes relevant for modeling of non-equilibrium plasmas that are developed for applications in micro and nanoelectronics, nanotechnologies, treatment of materials and biomedical applications.
The fundamental processes that are studied are chosen according to topical interests our experience and available experimental facilities. Those include measurements of transport coefficients, kinetic and non-hydrodynamic effects in dc and rf swarms, derivation of swarm normalized sets of cross sections, studies of nonlinear dynamical and self-organization phenomena in general, elementary processes at surfaces. Studies of swarms are strengthened by development of the new experiments designed for work with reactive gases of practical interest.
Furthermore, experimental studies and related modeling are performed to study breakdown and scaling of low pressure gas discharges and breakdown in micro discharges and at high frequencies. We study properties of single and two frequency capacitively and inductively coupled plasmas, atmospheric glow discharges, plasma needle, corona and dielectric barrier discharges.
Those discharges are employed in optimization of plasma applications such as etching, fast neutral etching, radiation therapy, pollution control, sterilization, and modification of organic materials, living cells and polymers.

Modeling and Numerical Simulations of Complex Physical Systems


Institution: Institut za Fiziku
Contractor: Ministry of Science of the Republic of Serbia
Contract type: National Research Project
Status: New
Begin: 01.01.2006. End: 31.12.2012.
Leadership: Dr. Aleksandar Belic
Contrnote:
The exponential growth of computing power has promoted scientific computing into a novel research tool and the method of choice to attack complex problems in physics, i.e. problems involving systems consisting of many bodies and/or having many degrees of freedom which are not easily amenable to standard experimental or theoretical investigations. Numerical modeling and simulations are heuristic tools making it possible to view new and previously inaccessible domains in science and to build up intuition on the new phenomenology. The goal of this process is to translate new-found intuition into better algorithms and new analytical results.

Project 141035 is built around the Scientific Computing Laboratory (best ranked EU centre of excellence in the region, under FP6 project CX-CMCS) and its state of the art computing, communication, and storage facilities. The purpose of the project is to harness these resources to gain key insight into the following research topics:

* Efficient calculation of path integrals
* Modeling and numerical simulations of granular systems
* Investigation of strongly correlated quantum systems
* Modeling of transport processes in the Earth-atmosphere system

Apart from the aforementioned research topics, we plan to continue ongoing research on related problems including modeling of gravitational accretion and the study of dynamics on scale-free networks.

Contractor: Ministry of Science and Environmental Protection
Contract type: National Research Project
Status: New
Begin: 01.01.2006. End: 31.12.2010.
Leadership: Dr. Branislav Jelenković
Contrnote:
We investigate interference and decoherence phenomena during light- matter interaction, related to the superposition of atomic states and electromagnetic fields and generated by the light with different degree coherence, using interferometric and holographic methods. We study fundamental and applied aspects of 1) Coherent Population Trapping, Electromagnetically Induced Transparency and Absorption due to near resonant polychromatic laser field excitation of levels in atomic vapour and cold atoms in the MOT; 2) Distant correlations of pairs of photons, atoms and molecules, and non-classical and non-local properties of polarized entangled photons; 3) Holographic properties of materials based on biological polymers doped with metallic ions of new types of photonic materials; 4) Environmental decoherence in systems of interacting qubits and transport of information in nets of excitable units;
From a scientific point of view this project leads to a more efficient use of several phenomena in quantum optics for preparation of quantum coherences, and in holography in micro-optics and photonic bandgap materials. From technological aspect this research leads to several applications of stabilized lasers in holography, metrology and nano-technology and entangled photons in quantum information.

Contract type: National Development Project
Status: New
Begin: 01.01.2005. End: 31.12.2007.
Leadership: Dr. Mirjana Tasić
Contrnote:
LIDAR (LIght Detection And Ranging) technique based on the elastic backscattering of the emitted laser radiation by the atmospheric aerosols, allows the real time visualization of the suspended particles with high temporal and spatial resolution. Elastic backscatter LIDAR proposed in this project is intended for remote detection of aerosols in the atmosphere, at the altitudes up to 5 km, with resolution of 50 m, as the most of aerosol loading is present in the first 3 km height. It is based on a pulsed Nd:YAG laser source with 532 nm, and 1064 nm wavelengths, and the received signals provide the time-height indication of the atmosphere on the basis of aerosol optical parameters such as the backscattering and/or the extinction coefficients. The proposed two wavelenght backscattering system is pointing vertically and is operated in coaxial mode. The received backscattered radiation will be detected by detection system including photomultiplier (532 nm) and avalanche photodiode (1064 nm). The results of LIDAR experimental measurements will be analyzed using Dust Regional Atmospheric Modeling (DREAM) system in the case of transport of mineral aerosol for Saharan dust outbreak transported to our country. Organized LIDAR measurements together with simulations with meteorological models provide a basic tool in studies of aerosol transport over Europe and its impact on European climate.

Leadership: Dr. Dejan Pantelić
Contrnote:
Nowadays, length standards are lasers, stabilized on some of appropriate molecular or atomic transitions. The aim of this project is to develop length standards according to recommendations of CIPM (International Comission for Weights and Measures). One of our goals is to develop a pair of stabilized, second harmonic, Nd-YAG lasers, as 532nm length standard. Active stabilization will be performed by saturated apsorption on iodine vapors. At the moment, we have constructed 1064 nm diode pumped Nd - YAG laser, which produced 375 mW of optical power at 1064 nm. We are developing a
method appropriate to force the laser into single longitudinal mode. Second harminic conversion is under development too. Also, a pair of stabilized diode lasers will be developed as 778 nm length standard. Laser will be activeli stabilized on two photon transition of rubidium. Until now, mechanics of the laser is completed and mounting of the laser and optical components is underway. Rubidium cell, with magnetic shielding and detection system is under development.

Contrnote:
Object of the project investigation is projecting and realization of an Automated Meteorological-Ecological System (AMES), which will be used for cement dust emission measuring and its atmospheric dispersion modeling near cement factory Lafarge-BFC in Beocin. Constitutive part of AMES is atmospheric dispersion software based on mathematical atmospheric dispersion model of Gaussian type: straight line model for routine emission and puff model for accidental emission pollutants to the atmosphere. Output from the software is continual field of air pollution distribution maximum 80 km away from air pollution source. Every ten minutes new meteorological data set starts atmospheric dispersion software (in accidental situations every minute), so every ten minutes or every minute operator has new information of air pollution distribution in vertical and horizontal direction. Besides software refreshes air pollution information practically in real time, it enables reconstruction of air pollution distribution in any past time covered with appropriate meteorological measurements and with appropriate information of air pollution emission.

Contrnote:
Within this research will be developed an automatic system for efficient reaction and notification in case of a railroad accident, while dangerous substances are being transported. Based on:
- tracking path of a train and determination of a correct position of a train at the moment of an accident,
- measuring meteorological parameters at the place of an accident, in real time and
- software for assessment of spreading contaminating substances trough the atmosphere,
this system will inreal time, track spreading of contaminating substances and enable making an estimate of the damage made on the environment at the place of an accident.
Based on this information, it would be possible to react according to the situation. The proposed project should enable data about the accident and assessment of endangerment of environment to be presented at ZTP and in appropriate information and alert centers. All data is automatically memorized with time entries, so it’s possible to reconstruct the accident that occurred. One particular part of software will be designed for simulating accidents.

Dual-Band and Triple-Band Metamaterial-Based Microwave Devices and Antennas for Modern Communication Systems


Institution: Institut za Fiziku
Contractor: Ministry of Science and Environmental Protection
Contract type: National Development Project
Status: New
Begin: 01.04.2008. End: 01.04.2010.
Leadership: Dr. Branka Jokanović
Contrnote:
In this project, the newest technology based on metamaterials will be applied. Metamaterials are artificial periodic structures which exhibit advantageous and unusual electromagnetic properties, generally not found in nature. They are composed of miniature unit cells whose size is typically smaller than one tenth of the propagating signal wavelength. Due to this fact, metamaterials can be considered as continuous media with effective dielectric permeability and effective magnetic permittivity. By a proper choice of the type and geometrical arrangement of constituent unit cells, the effective parameters of metamaterials can be made arbitrarily small or large, or even negative. By tailoring characteristics of the metamaterial according to the designer needs, RF and microwave circuits with improved performances can be obtained, such as small dimensions, dual- or triple-band operation, arbitrary antenna scanning angle, etc.

Double-negative (DNG) or left-handed (LH) metamaterials, which simultaneously exhibit negative effective permeability and negative effective permittivity in a certain frequency range, were first theoretically studied by Russian physicist Victor Veselago. The first structure that exhibits negative permittivity at microwave frequencies by decreasing the plasmon frequency was proposed in mid-nineties. Soon afterwards, negative permeability was obtained by a new sub-wavelength particle called split-rings resonator (SRR). By combining those two particles into one unit cell, the first experimental verification of LH behavior was performed in 2001.
Since the first experimental proof-of-principle some years ago, the field of metamaterials has seen a tremendous growth world-wide, as is testified by the exponential growth in publications dealing with this topic. Several programs within DARPA and DoE dedicated to this issue have been launched in the USA by several universities, but this topic is now also actively supported by Japan and China. Europe so far has been pioneering in several aspects, with a strong research base present, and with the tendency to structure the research community at a European level around a common strategic objective in this field.

The aim of the proposed project is the development of LH-metamaterial-based dual-band and triple-band microwave circuits and antennas. Due to the pronounced dispersion of LH metamaterials, circuits that simultaneously operate in two or even three arbitrary frequency bands can be designed. This is extremely important for microwave links that operate in precisely defined frequency bands according to ITU recommendations. In the conventional technology, every link has separate microwave transceiver which depends on the operating frequency: 4GHz, 7.5GHz, 13GHz, 15GHz, 18GHz, 23GHz and 26GHz, while the baseband processing is the same for all, and depends on the capacity of the system, i.e. the transmission rate. The prices of microwave links are constantly dropping, due to the great demand of the mobile-telephony market. It seems that the application of new technologies is the only way to insure survival of small producers, such as IMTEL Communications. By applying dual-band circuits in microwave transceiver, the number of different microwave circuits that need to be designed and fabricated would be significantly reduced, which would allow application of the same hardware on two or three operating frequency bands. By using the conventional technology, maximally two harmonic-related frequency bands can be covered simultaneously, while application of metamaterials allows usage of two or three arbitrary (non-harmonic related) frequency bands. This is due to highly nonlinear dispersion characteristic of metamaterials.

The need for dual- or, generally, multi-band circuits exists also in personal wireless communication systems for Internet access, such as lap-top computers, PDA, iPOD, etc. In all these applications microwave multi-band circuits with standard number of ports are used.

Dual- or multi-band operation is also important for wireless sensors for heart-rate monitoring (EKG recording) and monitoring of respiratory organs. In such systems, multi-band multi-port components are used, due to the fact that microwave circuit or antenna must have a separate access for every operating frequency, since signal processing performed on different frequencies allows separation of the signal caused by heart operation from that caused by respiration.

In this project, multi-band circuits with standard number of ports will be designed, for the application in microwave links and personal devices for Internet access, as well as multi-band circuits and antennas with separate ports for each operating frequency band.

DEVELOPMENT OF PILOT SYSTEM FOR THE AUTOMATIC PREVENTION ASH LIFTING FROM ASHES DEPOTS


Institution: Institute of physics
Contractor: Ministry of Science and Technological Development, Serbia
Contract type: National Development Project
Status: New
Begin: 01.04.2008. End: 31.12.2010.
Leadership: Dr. Dragan Dramlić
Contrnote:
Dust and ash, lifted from coal and ashes depots of thermal power, or from open-cut mining, significantly contributes to the pollution of the environment close to these structures. Transportation of dust and ash by wind, attenuation of its concentration in the air caused by atmospheric diffusion and dry deposition, are the most important mechanisms that affect the concentration of dust in the air and its precipitated quantities on the soil. Unfavorable physical and chemical characteristics of ash and law speed wind, lead to ash lifting. Under the unfavorable meteorological conditions, such as dry weather with strong winds, episodic pollutions are frequent. The problem is even bigger because depots are often in the immediate surroundings of settlements and agricultural areas. Ash depots are surface pollution sources, activated by unfavorable weather conditions. Ash depots are usually sprinkled by water, through processes of moisturizing and forming „water miror“, in order to minimize and/or disable ash emission.

Contract type: International Project
Status: New
Begin: 01.04.2006. End: 31.03.2008.
Leadership: Dr. Aleksandar Belic
Contrnote:
The Enabling Grids for E-sciencE project brings together scientists and engineers from more than 90 institutions in 32 countries world-wide to provide a seamless Grid infrastructure for e-Science that is available to scientists 24 hours-a-day. Conceived from the start as a four-year project, the second two-year phase started on 1 April 2006, and is funded by the European Commission. Expanding from originally two scientific fields, high energy physics and life sciences, EGEE now integrates applications from many other scientific fields, ranging from geology to computational chemistry. Generally, the EGEE Grid infrastructure is ideal for any scientific research especially where the time and resources needed for running the applications are considered impractical when using traditional IT infrastructures. The EGEE Grid consists of over 35,000 CPU available to users 24 hours a day, 7 days a week, in addition to about 13 Petabytes (13 million Gigabytes) of storage, and maintains 35,000 concurrent jobs on average. Having such resources available changes the way scientific research takes place. The end use depends on the users needs: large storage capacity, the bandwidth that the infrastructure provides, or the sheer computing power available.

The establishment of collaborative models for use of computing and data resources across various domains all over Europe and worldwide is currently being pursued through several eInfrastructure efforts. In this context, the SEE-GRID regional initiative has recently demonstrated that a geographically-independent, common-pool of computing resources can be of substantial scientific value to a widely distributed, less-resourced region like South-East Europe (SEE). Through the interconnection of the SEE regional infrastructure to the pan-European and worldwide eInfrastructures, the developing SEE sites can benefit from accessing computing power and advanced applications that would otherwise be unfordable, and thus help make real the fundamental objective of minimizing the digital divide in SEE and ensuring equal opportunities for every citizen in the region.

The strategic objective of the CX-CMCS project is to transform the Scientific Computing Laboratory into a centre of excellence, i.e. to decisively increase the quality of research conducted at SCL, and make it a preferred West Balkan research partner for EU institutions working in the fields of simulation of complex systems and of GRID technology. SCL is a unit of the Institute of Physics in Belgrade. The Institute contributes more than 10% of the total scientific output of Serbia and constantly ranks among the best R&D institutions in the region. SCL currently has 17 staff members, and participates in several international and national projects, including FP6 projects CX-CMCS, SEE-GRID, SEE-GRID-2, EGEE-II, and Cost action P10 (Physics of Risk). SCL defines the current state of the art in high performance computing in the West Balkan region with its PARADOX cluster. CX-CMCS aims to reinforce the research capacity of the SCL by: hiring young researchers; providing training and mobility for the research staff; upgrading the computing infrastructure. The success of this endeavor will be measured through a benchmarking exercise to be performed in the projects last year. Our networking partners (4 from EU and 3 from Serbia) have been carefully selected to provide the skills and expertise necessary to reinforce the research potential of SCL through training and joint research. The proposed equipment upgrade will make it possible to tackle even the most complex GRID applications allowing SCL to become a key regional player in deployment and use of this emerging technology. The CX-CMCS International Advisory Board will help SCL develop a long term strategy and facilitate its integration into ERA.

The ability to understand, manipulate and control chemical reactions at the molecular level is one of the great challenges of modern research. Since chemical processes are dominant in most areas of science and technology, the ability to control their pathways provides exciting new opportunities that may be exploited by both the research and technological communities. Such ‘single molecule engineering’ requires selective bond cleavage in target molecules to allow subsequent management of the local site chemistry. In electron beam experiments it is well established that low energy electrons offer this selectivity with high efficiency, a selectivity that is controllable by simply ‘tuning’ the electron energy.Recently, low energy electrons derived from the tip of a scanning tunnelling microscope have also been used to control bond rupture and subsequent linkage of individual molecules to the substrate. This Action aims at an interdisciplinary European programme to combine state-of-the-art in electron induced chemistry and surface science with these recent advances in scanning tunnel microscopy to pioneer a new field of ‘Electron Controlled Chemical Lithography’, with the prospect of designer synthesis down to the nanoscale and electron controlled manipulation of surface properties with spatial resolution ranging from the millimetre down to the nanometre scale.

Contrnote:
A new state of nuclear matter, called quark gluon plasma (QGP), consists of interacting quarks, antiquarks and gluons, which are no longer confined. One of the major goals of RHIC (Relativistic Heavy Ion Collider) and LHC (Large Hadron Collider) experiments is to create and explore QGP. The main goal of this project is to develop a realistic theoretical formalism and to generate numerical predictions, which will be directly compared with main experimental observables that are used to map properties of QGP.
