Dissipation, Noise, and Vacuum Decay in Quantum Field Theory

Mostrar todas las versiones(2)

We study the process of vacuum decay in quantum field theory focusing on the stochastic aspects of the interaction between long- and short-wavelength modes. This interaction results in a diffusive behavior of the reduced Wigner function describing the state of long-wavelength modes, and thereby to a...
