Quantum instability in a dc-SQUID with strongly asymmetric dynamical parameters
A. U. Thomann, V. B. Geshkenbein, G. Blatter
A classical system cannot escape out of a metastable state at zero temperature. However, a composite system made from both classical and quantum degrees of freedom may drag itself…

The dynamically asymmetric SQUID: Münchhausen effect
A. U. Thomann, V. B. Geshkenbein, G. Blatter
We report on a complex zero-temperature decay channel of a classical object in a metastable state coupled to a quantum degree of freedom. This setting can be realized in a dc-SQUID…
