Coherent and incoherent chaotic tunneling near singlet-doublet crossings
Sigmund Kohler, Ralf Utermann, Peter Hanggi +1
In the spectrum of systems showing chaos-assisted tunneling, three-state crossings are formed when a chaotic singlet intersects a tunnel doublet. We study the dissipative quantum d…

Tunneling And The Onset Of Chaos In A Driven Bistable System
R. Utermann, T. Dittrich, P. Hanggi
We study the interplay between coherent transport by tunneling and diffusive transport through classically chaotic phase-space regions, as it is reflected in the Floquet spectrum o…
