Hidden time-nonlocal Floquet symmetries
Sigmund Kohler, Jesús Casado-Pascual
We investigate the Floquet spectrum of a detuned, driven two-level system and show that it exhibits exact quasienergy crossings when the detuning is an integer multiple of the ener…

The open driven two-level system at conical intersections of quasienergies
Sigmund Kohler
We study the stationary state of an ac-driven two-level system under particle exchange with a fermionic environment. A particular question addressed is whether there exist limits i…
