Abstract

I will present our recent and ongoing work on proposed realizations, detection, and applications of non-equilibrium topological phases of matter engineered and stabilized by external periodic drives. These include Floquet topological insulators and superconducting phases that can support multiple topological bound states, various phases of irradiated graphene under circularly polarized lasers, and higher-order topological phases that support corner and bulk bound states. I will also discuss novel dynamical responses of driven systems and Floquet gauge pumps as probes of protected many-body degeneracies. A central theme of this work is the exquisite in-situ control offered by Floquet engineering allowing the realization and study of novel quantum phases of matter.
