Condensed matter physics

Terahertz spectroscopy is a powerful tool in condensed matter. Moreover, we use the method of molecular dynamics calculations, in order to explore the phenomenon with a resolution at the level of individual elements.

Main research directions:

  • Common problems in terahertz spectroscopy of condensed matter. Terahertz spectroscopy of liquids and solids, phase transitions
  • Nonequilibrium phenomena in classical condensed matter in the external heat and force fields. Study of 2D systems of particles. Fundamental problems of producing THz devices based on graphene structures
  • Pair correlations in crystals. Crystallization from the glassy state. Homogeneous and heterogeneous crystal nucleation in supercooled melts
  • Investigation of the long-range interactions impact on the general hydrodynamic phenomena. Investigation of the dynamics and structure of the liquid interface and instabilities at the kinetic level, also investigation of the rheology impact on the hydrodynamic instability

Optical strongly correlated systems and spectroscopic methods

Our research in this field combine experiments (terahertz pulsed spectroscopy and femtosecond optical pulses), simulations (numerical solution of Maxwell's equations using the finite difference method) and the development of new algorithms for post-processing based on the solutions of ill-posed inverse problems
