Piecewise linear potentials for false vacuum decay and negative modes
Wen-Yuan Ai, Jean Alexandre, Sarben Sarkar
We study bounce solutions and associated negative modes in the class of piecewise linear triangular-shaped potentials that may be viewed as approximations of smooth potentials. In…

False vacuum decay rates, more precisely
Wen-Yuan Ai, Jean Alexandre, Sarben Sarkar
We develop a method for accurately calculating vacuum decay rates beyond the thin-wall regime in a pure scalar field theory at the one-loop level of the effective action. It accoun…
