Albert Verdeny, Andreas Mielke, Florian Mintert: Accurate effective Hamiltonians via unitary flow in Floquet space
Phys. Rev. Lett.111, 175301 (2013) .

Abstract

We present a systematic construction of effective Hamiltonians of periodically driven quantum systems. Due to an equivalence between the time dependence of a Hamiltonian and an interaction in its Floquet operator, flow equations, that permit to decouple interacting quantum systems, allow us to identify time-independent Hamiltonians for driven systems. With this approach, we explain the experimentally observed deviation of expected suppression of tunneling in ultra-cold atoms.
