Zero-resistance state in ac-driven two-dimensional electron gas and

Host: Gleb Finkelstein
One of the most exciting and surprising recent experimental finding in
matter physics was the independent discovery by M. Zudov and co-workers
(University of Utah) and R. Mani and co-workers (Harvard) that a two
electron gas placed in a dc magnetic field and exposed to microwave
displays the oscillatory resistivity and finally achieves a state of
zero electrical resistance.
I will discuss the phenomenological model of such a state proposed
by A.V. Andreev, I.L. Aleiner and A.J. Millis as well as different
microscopic mechanisms of the oscillatory photoresistivity.
