Phases of Quasiperiodic Driving

This event is part of the Graduate Student Council Events.

Part of the student seminar series. A recording will be posted on the event page.

Periodically driven quantum systems have been a topic of much study in recent years, and we now arguably have a good understanding of the kinds of behavior they can exhibit. At the other end of driving complexity, a completely unstructured drive should produce an unstructured response. However, there is a very long way between "periodic" and "no structure", and this is a regime that has not been well explored. Quasiperiodic driving is arguably the smallest step into this uncharted territory we can make from the periodic side. This talk will elaborate on recent work exploring what kind of new features quasiperiodically driven quantum systems might exhibit that periodically driven systems do not, and also the ways in which the large amount of structure in periodically driven systems may persist. We exploit an analogy to condensed matter physics to describe these differing behaviors as belonging to different phases of the driven system.
