Inducing long-lived non-equilibrium electronic phases with time-periodic drives

Floquet engineering - designing phases of matter “on-demand" using time-periodic drives has recently emerged as a powerful tool for inducing exotic non-equilibrium phenomena. This talk will focus on Floquet phases arising in steady states and quasi-steady states of periodically driven interacting electronic systems. In the first part of my talk, I will discuss a spontaneously broken symmetry phase in the steady-state of a laser-driven semiconductor coupled to reservoirs of phonons and photons. In the second part, I will consider slowly driven one-dimensional electronic systems and show that despite strong interactions between the electrons, these systems can form exponentially long quasi-steady states exhibiting universal transport.
