Periodically Driven Quantum Systems

July 21, 2017 - 4:00pm
Speaker: 
Paraj Titum
Institution: 
JQI & QuICS
Periodically driven systems (also known as Floquet systems) have seen a lot of recent theoretical and experimental interest. In this talk, I will provide a survey of various examples of Floquet systems. I will start by explaining basic Floquet theory, and describe how to obtain the dynamics of such driven systems. Then I will show how periodic driving can be used to tune a trivial system into a desired topological phase of matter. Finally, I will discuss interacting Floquet phases and the problem of heating in these systems. If time permits, I will describe the recent realization of a new phase of matter - time crystals.
