We shall develop theoretical and computational methods for description of resonance-dominated atomic and molecular radiation and collision processes. Relationship between lifetimes of resonant states and their phase-space structure will be investigated. Atomic collision processes close to thresholds will be studied. We shall investigate quantum-mechanical models for fast ion-atom collisions with two actively participating electrons. Interaction of atoms with solid surfaces will be studied including the ionization of Rydberg atoms and ions within the framework of asymptotic models. Computational and theoretical investigations of many-electron correlations and relativistic effects in atomic processes and in structure of atomic shells will be performed. Photoionization and photoemission spectra of atoms and molecules exposed to intense laser fields will be calculated by using Floquet method and numerical solution of the time dependent Schrodinger equation. Starting from the crucial role of electronic correlations in the structure and transport through quantum dots, the few-electron dots will be studied, particularly in an external magnetic field. The electronic transport through nano-heterostructures (superconducting and nanowire-DNA-nanowire junction) will be studied theoretically and experimentally. We shall investigate theoretically and numerically pure and mixed quantum states that are of importance in quantum optics and quantum information theory.
