Author(s): Thomas Iadecola and Timothy H. Hsieh We show that time-reflection symmetry in periodically driven (Floquet) quantum systems enables an inherently nonequilibrium phenomenon structurally similar to quantum-mechanical supersymmetry. In particular, we find Floquet analogs of the Witten index that place lower bounds on the degeneracies of s... [Phys. Rev. Lett. 120, 210603] Published Thu May 24, 2018
