Decoherence, tunneling, and noise-induced activation in a double-potential well at high and zero temperature
We study the effects of the environment on tunneling in an open system described by a static double-well potential. We describe the evolution of a quantum state localized in one of the minima of the potential at t=0, in both the limits of high and zero environment temperature. We show that the evolu...
