Floquet Conformal Field Theory

ORAL

Abstract

Conformal field theory provides an ideal platform to discuss examples of Floquet dynamics in an analytic and exact way. Earlier work solved for the Floquet dynamics using a particular driving Hamiltonian (the sl(2,R) generators) and restricted initial state (eigenstates). In this talk, we will generalize the original set-up to go beyond the sl(2,R) algebra and also discuss driving a thermal state. We will discuss the entanglement pattern and energy profile in these generalized set-ups and also describe some non-unversal features of the Floquet dynamics.
