Macroscopic tunneling, decoherence and noise-induced activation

Mostrar todas las versiones(3)

We study the effects of the environment at zero temperature on tunneling in an open system described by a static double-well potential. We show that the evolution of the system in an initial Schrödinger cat state, can be summarized in terms of three main physical phenomena, namely decoherence, quant...
