Research Focus

Condensed matter theory: spintronics, spin transfer torque, spin currents.
Motion of electrons leads not just to electric charge transport but also to spin transport. Since spin is intrinsically connected with angular momentum, many interesting phenomena are produced by spin currents. In particular, their interactions with magnetic textures, such as domain walls, skyrmions, etc., leads to controlled motion of magnetic defects. Controlled magnetic defects can be then used for technological purposes in computer memory units.
