A proposal for a vacuum wavefunctional in FRW spaces
Enrique Álvarez
The approximate late conformal time wavefunctional for self-interacting scalar quantum fields in Friedmann-Robertson-Walker spaces is computed. It is a good candidate for the {\em…

Finite Time Vacuum Survival Amplitude and Vacuum Energy Decay
Enrique Álvarez, Roberto Vidal
The problem of the vacuum energy decay is studied for both signs of the cosmological constant, through the analysis of the vacuum survival amplitude, defined in terms of the {\em c…
