My research interests include fluctuation phenomena far from thermal equilibrium, transport in correlated electron systems, nonlinear vibrations, nonlinear optics of solids, and quantum information.

An example: modulated quantum systems, including those used in quantum information processing, display a new mechanism of interstate switching. It differs from the conventional quantum tunneling and thermal activation. In switching, quantum fluctuations drive the system over the quasienergy barrier. We call it quantum activation.

This image represents a conceptualization of the mechanism of quantum activation.
