    "abstract": "In the spectrum of systems showing chaos-assisted tunneling, three-state\ncrossings are formed when a chaotic singlet intersects a tunnel doublet. We\nstudy the dissipative quantum dynamics in the vicinity of such crossings. A\nharmonically driven double well coupled to a bath serves as a model. Markov and\nrotating-wave approximations are introduced with respect to the Floquet\nspectrum of the time-dependent central system. The resulting master equation is\nintegrated numerically. We find various types of transient tunneling,\ndetermined by the relation of the level width to the inherent energy scales of\nthe crossing. The decay of coherent tunneling can be significantly retarded or\naccelerated. Modifications of the quantum asymptotic state by the crossing are\nalso studied. The comparison with a simple three-state model shows that in\ncontrast to the undamped case, the participation of states outside the crossing\ncannot be neglected in the presence of dissipation.",
