Exact one-loop false vacuum decay rate
Victor Guada, Miha Nemevšek
We discuss an exact false vacuum decay rate at one loop for a real and complex scalar field in a quartic-quartic potential with two tree-level minima. The bounce solution is used t…

FindBounce: package for multi-field bounce actions
Victor Guada, Miha Nemevšek, Matevž Pintar
We are launching FindBounce, a Mathematica package for the evaluation of the Euclidean bounce action that enters the decay rate of metastable states in quantum and thermal field th…

Multifield Polygonal Bounces
Victor Guada, Alessio Maiezza, Miha Nemevšek
We propose a new approach for computing tunneling rates in quantum or thermal field theory with multiple scalar fields. It is based on exact analytical solutions of piecewise linea…
