The units investigate problems of condensed state theory, and thematic areas of research are quantum transport in low-dimensional structures, low-dimensional quantum materials, quantum graphs and networks, quantum technologies, and modeling of charge dynamics in conducting polymers. In addition, the Condensed Matter Physics unit investigates newly discovered superconducting substances within the microscopic and macroscopic Ginzburg-Landau theory, taking into account the multi-zone and anisotropy effects. Also, the dynamics of new point and long Josephson systems, their use as quantum bits, the influence of soliton propagation and frustration effects in these systems, the electric field, and the Rashba-Dresselhaus spin-orbital interaction are theoretically studied.
