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

Igor L Aleiner


Tuesday April 5, 11:30 am, Room 234, Physics Building

Host: Gleb Finkelstein


One of the most exciting and surprising recent experimental finding in condensed 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 dimensional electron gas placed in a dc magnetic field and exposed to microwave radiation 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.
