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…
Exact Tunneling Solutions in Multi-Field Potentials
J. R. Espinosa, T. Konstandin
The tunneling potential formalism makes it easy to construct exact solutions to the vacuum decay problem in potentials with multiple fields. While some exact solutions for single-f…
Bubbles of Nothing: The Tunneling Potential Approach
J. J. Blanco-Pillado, J. R. Espinosa, J. Huertas +1
Bubbles of nothing (BoNs) describe the decay of spacetimes with compact dimensions and are thus of fundamental importance for many higher dimensional theories proposed beyond the S…
Tunneling Potentials to Nothing
J. J. Blanco-Pillado, J. R. Espinosa, J. Huertas +1
The catastrophic decay of a spacetime with compact dimensions, via bubbles of nothing (BoNs), is probably a generic phenomenon. BoNs admit a 4-dimensional description as singular C…
Vacuum Decay Actions from Tunneling Potentials for General Spacetime Dimension
J. R. Espinosa, J. -F. Fortin
The tunneling potential method to calculate the action for vacuum decay is an alternative to the Euclidean bounce method that has a number of attractive features. In this paper we…
Pseudo-Bounces vs. New Instantons
J. R. Espinosa, J. Huertas
Some false vacua do not decay via bounces. This usually happens when a flat direction of the tunneling action due to scale invariance is lifted to a sloping valley by a scale break…
