Dissipation, noise, and vacuum decay in quantum field theory

Mostrar todas las versiones(2)

The process of vacuum decay in quantum field theory focusing on the stochastic aspects of the interaction between long and short wavelength modes was studied. The interaction resulted in a diffusive behavior of the reduced Wigner function describing the state of long wavelength modes and a finite ac...

description The process of vacuum decay in quantum field theory focusing on the stochastic aspects of the interaction between long and short wavelength modes was studied. The interaction resulted in a diffusive behavior of the reduced Wigner function describing the state of long wavelength modes and a finite activation rate at zero temperature. A substantial contribution was made to the total decay rate by the effect.
