The standard vacuum bounce formalism suffers from inconsistencies when applied to
thermal bubble nucleation, for which ad hoc workarounds are commonly adopted …

A bstract We provide a method to calculate the rate of false vacuum decay induced by a
black hole. The method uses complex tunneling solutions and consistently takes into …

A bstract We study false vacuum decay catalyzed by black holes. We consider a toy two-
dimensional model of a scalar field with an unstable potential in the background of a dilaton …

In flat space and at finite temperature, there are two regimes of false vacuum decay in
quantum field theory. At low temperature, the decay proceeds through thermally-assisted …

A bstract We present the calculation of the Feynman path integral in real time for tunneling in
quantum mechanics and field theory, including the first quantum corrections. For this …

We develop a method for accurately calculating vacuum decay rates beyond the thin-wall
regime in pure scalar field theory at the one-loop level of the effective action. It accounts for …

A bstract Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated.
The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the …

In the context of false vacuum decay at zero temperature, it is well known that bubbles
expand with uniform proper acceleration. We show that this uniformly accelerating …

We study a false vacuum decay in a two-dimensional black hole spacetime background. The
decay rate in the case that a nucleation site locates at a black hole center has been …

When a quantum field is in contact with a thermal bath, the vacuum state of the field may be
generalized to a thermal vacuum state, which takes into account the thermal noise. In thermo …
