Finite time vacuum survival amplitude and vacuum energy decay
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 conformal time, z, by Aðz; z0Þ hvac zjvac z0i. Transition amplitudes are computed for finite time span, Z z0 z, and their late time behavior (directly related to the putative decay width of the state), and the transients ar...
متن کاملInterpreting Cosmological Vacuum Decay
The cosmological vacuum decay scenario recently proposed by Wang and Meng [1] is rediscussed. From thermodynamic arguments it is found that the ǫ parameter quantifying the vacuum decay rate must be positive in the presence of particle creation. If there is no particle creation, the proper mass of Cold Dark Matter (CDM) particles is necessarily a time dependent quantity, scaling as m(t) = moa(t)...
متن کاملFalse Vacuum Decay after Inflation
Inflation is terminated by a non-equilibrium process which finally leads to a thermal state. We study the onset of this transition in a class of hybrid inflation models. The exponential growth of tachyonic modes leads to decoherence and spinodal decomposition. We compute the decoherence time, the spinodal time, the size of the formed domains and the homogeneous classical fields within a single ...
متن کاملParticle decay in false vacuum
We revisit the problem of decay of a metastable vacuum induced by the presence of a particle. For the bosons of the 'master field' the problem is solved in any number of dimensions in terms of the spontaneous decay rate of the false vacuum, while for a fermion we find a closed expression for the decay rate in (1+1) dimensions. It is shown that in the (1+1) dimensional case an infrared problem o...
متن کاملVacuum Decay via Lorentzian Wormholes
We speculate about the spacetime description due to the presence of Lorentzian wormholes (handles in spacetime joining two distant regions or other universes) in quantum gravity. The semiclassical rate of production of these Lorentzian wormholes in Reissner Nordström spacetimes is calculated as a result of the spontaneous decay of vacuum due to a real tunneling configuration. In the magnetic ca...
