SUMMARY:Inducing non-equilibrium phases in semiconductors with time-pe
 riodic drives\, R. G. Herb Condensed Matter Seminar\, Ilya Esin\, Calt
 ech
DESCRIPTION:“Floquet engineering” - designing band structures “o
 n-demand" through an application of coherent time-periodic drives\, ha
 s recently emerged as a powerful tool for inducing exotic phenomena in
  ordinary materials. In this talk\, I will discuss the application of 
 Floquet engineering for inducing novel non-equilibrium phases of matte
 r in steady states of time-periodically driven semiconductors. The ste
 ady states are achieved due to the interplay between the coherent exte
 rnal drive\, electron-electron interactions\, and dissipative processe
 s arising from the coupling to phonons and the electromagnetic environ
 ment. I will show that despite the highly non-equilibrium nature of th
 ese systems\, by judicially choosing the properties of the material\, 
 the external drive\, and the environments\, their steady states can ex
 hibit topological transport and strongly correlated phases such as a n
 ovel electronic liquid gyro-crystalline phase.
