dc.titleEffective Hamiltonians, prethermalization, and slow energy absorption in periodically driven many-body systems

dc.description.abstractenWe establish some general dynamical properties of lattice many-body systems that are subject to a high-frequency periodic driving. We prove that such systems have a quasi-conserved extensive quantity H∗, which plays the role of an effective static Hamiltonian. The dynamics of the system (e.g., evolution of any local observable) is well-approximated by the evolution with the Hamiltonian H∗ up to time τ∗, which is exponentially long in the driving frequency. We further show that the energy absorption rate is exponentially small in the driving frequency. In cases where H∗ is ergodic, the driven system prethermalizes to a thermal state described by H∗ at intermediate times t≲τ∗, eventually heating up to an infinite-temperature state at times t∼τ∗. Our results indicate that rapidly driven many-body systems generically exhibit prethermalization and very slow heating. We briefly discuss implications for experiments which realize topological states by periodic driving.
