Pump-probe scheme for electron-photon dynamics in hybrid conductor-cavity systems
At weak disorder strenghts the wavefunction in the two-dimensional electron gas
is delocalized due to the spin-orbit coupling. At critical disorder a localization transition takes place.

Carrier mediated interaction
The goal of this study is to find natural magnetic phase of the system and
take this into account in calculations of the spin Hall conductivity.
Double exchange ferromagnetic materials
Orbital polaron in ferromagnets
In the spectral function of double exchange ferromagnets, we observe in the upper-Hubbard bands the characteristic three-band structure. The polaron near the Fermi energy is a result of the mechanism that allows electrons to move around in the lattice near quarter filling (n=1). Without the polaron the energy cost of moving around through the lattice would increase proportionally to the length of the path covered by the electron, so the electron would be localized.

Disordered double exchange impurities
Disorder in a system with correlated magnetic impurities in an uncorrelated host material are treated using
the "Shiba" coherent potential approximation.
