Decoherence in resonantly driven bistable systems

We study dissipative tunneling in a double well potential that is driven close to a resonance between the lowest tunnel doublet and a singlet. While the coherent dynamics can be described well within a three-level approximation, dissipative transitions to levels outside the singlet and the doublet may play a crucial role. Moreover, such transitions can enhance the entropy production significantly.
