Macroscopic quantum tunneling with decoherence
Esteban Calzetta, Enric Verdaguer
The tunneling probability for a system modelling macroscopic quantum tunneling is computed. We consider an open quantum system with one degree of freedom consisting of a particle t…

Activation-like processes at zero temperature
Daniel Arteaga, Esteban Calzetta, Albert Roura +1
We examine the possibility that a metastable quantum state could experiment a phenomenon similar to thermal activation but at zero temperature. In order to do that we study the rea…
