Theoretical Solid State Physics

Theoretical Solid State Physics

The department of Theoretical Solid State Physics is there to provide theoretical background to experimental and applied research. Also to perform, initiate and participate in world class theoretical research efforts.

 

Main fields of our reseach work:

  • Determination of phase-diagrams of spin-ladders using density matrix- renormalization group method
  • Mapping of the self-states of the one-dimensional attractive Hubbard- model using Bethe Ansatz
  • Consequences of magnetic impurities in mesoscopic metals.
  • Investigation of connections between two-level systems and various Kondo-models using renormalization group method
  • Interpretation of the results of Raman-scattering with the help of the bilayer-model
  • Investigation of magnetic anisotropy of thin layers considering the spin- orbit coupling, Kondo-effect, and relativistic effects
  • Determination of atomic volume, and elastic properties of transition metals using full charge-density techique.
  • Conditions of ferromagnetic order formation in lattice models. Investigation of the connection between Kondo lattice-and band ferromagnetism in correlated two-band model.
  • Investigation of the dinamic exponents of non-equilibrium phase transitions in the kinetic Ising model.
  • Determination of dinamic properties and self-states of Bose-condensed gases.

The staff of the department is traditionally participating in education, teaching Solid State physics at various levels.

The Complex Systems Research Group deals with the cooperative behavior, ordering, equilibrium and far from equilibrium dynamics of interacting systems with many degrees of freedom. Our main research topics are the following...
