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…

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 false-vacuum decay rate in the thin-wall approximation
Marco Matteini, Miha Nemevšek, Lorenzo Ubaldi
We present a fully analytical calculation of the false vacuum decay rate for a self-interacting scalar field in the thin-wall approximation. We obtain the bounce solution, together…
