Brillouin-Wigner theory for high-frequency expansion in periodically driven systems: Application to Floquet topological insulators

Takahiro Mikami, Sota Kitamura, Kenji Yasuda +3

We construct a systematic high-frequency expansion for periodically driven quantum systems based on the Brillouin-Wigner (BW) perturbation theory, which generates an effective Hami…
