Floquet insulators and lattice fermions beyond naive time discretization
Periodically driven quantum systems known as Floquet insulators can host topologically protected bound states known as “π modes” that exhibit response at half the frequency of the drive. Such states can also appear in undriven lattice field theories when time is discretized as a result of fermion do...
