The Tunneling Potential Approach to Q-Balls
José Ramon Espinosa, Julian Heeck, Mikheil Sokhashvili
Q-balls are bound-state configurations of complex scalars stabilized by a conserved Noether charge Q. They are solutions to a second-order differential equation that is structurall…
Thick Wall from Thin Walls
J. R. Espinosa
An Euclidean bounce describing vacuum decay can be considered as an infinite stack of concentric thin shells to which a thin-wall action can be assigned. The integral over all shel…
Tunneling Potential Actions from Canonical Transformations
José R. Espinosa, Ryusuke Jinno, Thomas Konstandin
A new formulation for obtaining the tunneling action for vacuum decay based on the so-called tunneling potential was developed recently. In the original derivation, the new action…
Exactly Solvable Vacuum Decays with Gravity
J. R. Espinosa, J. -F. Fortin, J. Huertas
Using a new approach to the analysis of false vacuum decay based on the so-called tunneling potential, we develop a general method to find scalar potentials with a false vacuum wit…
The Stabilizing Effect of Gravity Made Simple
J. R. Espinosa
A new approach to vacuum decay in quantum field theory, based on a simple variational formulation in field space using a tunneling potential, is ideally suited to study the effects…
Vacuum Decay in the Standard Model: Analytical Results with Running and Gravity
J. R. Espinosa
A tunneling bounce driving the decay of a metastable vacuum must respect an integral constraint dictated by simple scaling arguments that is very useful to determine key properties…
