Research Interests

My field of research is computational/theoretical nanophysics. Current research concerns investigation of charge and spin transport in molecules, semiconductor structures and other submicron electronic devices. This work includes investigation of fundamental aspects of transport in nano-scale systems, electron and nuclear spin relaxation mechanisms, simulation of dynamic of spin systems, study the influence of nuclear spin polarization on the electron system and vice-versa. Some of this work has focused on novel approaches to semiconductor device functioning, e.g. potential applications of nanostructures to quantum information and quantum computing. I am also interested in different aspects of transport in biological systems.

Some recent projects have investigated: radiation-induced currents in quantum wires and quantum rings; propagation of spin polarized electrons through boundary between different semiconductors; electron spin relaxation in antidot lattices; measuring nuclear spin polarization by electron current; quantum computing with nuclear spins in mesoscopic systems.
