The theory of false vacuum decay in a thermal system may have cross-over from predominantly transitions to quantum as the temperature is decreased. New numerical methods and results are presented here that can be used model bubble nucleation this regime for cosmology laboratory analogues early universe phase transitions.

Pair production in a constant electric field is closely analogous to bubble nucleation false vacuum. The classical trajectories of the pairs are Lorentz invariant, but this invariance should be broken by process. Garriga et al. used model detector, consisting other particles interacting with pairs, investigate how pair seen different Lorentzian observers. They found that (antiparticles) predomi...

We discuss the computation of quantum effective action strongly interacting field theories using holographic duality and its use to determine quasiequilibrium parameters first-order phase transitions relevant for gravitational wave production. A particularly simple model is introduced, containing only metric a free massive scalar field. Despite simplicity, contains rich diagram, including at no...

We present a study of the role of fermions in the decay of metastable states of a scalar field via bubble nucleation. We analyze both one and threedimensional systems by using a gradient expansion for the calculation of the fermionic determinant. The results of the one-dimensional case are compared to the exact results of previous work.
