False Vacuum Decay Rate From Thin To Thick Walls
Marco Matteini, Miha Nemevšek, Yutaro Shoji +1
We consider a single real scalar field in flat spacetime with a polynomial potential up to , that has a local minimum, the false vacuum, and a deeper global minimum, the true…

Analytic thin wall false vacuum decay rate
Aleksandar Ivanov, Marco Matteini, Miha Nemevšek +1
We derive a closed-form false vacuum decay rate at one loop in the thin wall limit, where the true and false vacua are nearly degenerate. We obtain the bounce configuration in …

From vacuum decay to gravitational waves
Marco Matteini
I present a recap of a fully analytical calculation of the Euclidean action for a self-interacting scalar field with a quartic potential, in the thin-wall approximation. I then app…
