Quantum and Optical Interferometry

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.
