Globally Charged Vacuum Decay
Giulio Barni, Jose R. Espinosa
Vacuum decay at zero temperature is generically described by a real -symmetric Coleman bounce. When the scalar field driving the decay carries a conserved global charge, this…

A positive definite formulation of vacuum decay with reduced symmetry
José R. Espinosa, Ryusuke Jinno, Thomas Konstandin +2
The Euclidean bounce for vacuum decay enjoys an symmetry that is lost in the presence of impurities than can catalyze the decay. We present a formulation for the calculation…

An Exploration of Vacuum-Decay Valleys
J. R. Espinosa, T. Konstandin
In the standard lore the decay of the false vacuum of a single-field potential is described by a semi-classical Euclidean bounce configuration that can be found using overshoot/und…
