Effective Hamiltonians, prethermalization, and slow energy absorption in periodically driven many-body systems
Effective Hamiltonians, prethermalization, and slow energy absorption in periodically driven many-body systems
We establish some general dynamical properties of quantum many-body systems that are subject to a high-frequency periodic driving. We prove that such systems have a quasiconserved 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 …
