Reconsidering the calculation of the false vacuum decay rate at zero temperature
Qiang Yin
In the calculation of the decay rate at finite temperature using the saddle point approximation, we identified some inconsistencies in the calculation of the decay rate at zero tem…

Saddle-point approximation to the false vacuum decay at finite temperature in one-dimensional quantum mechanics
Koji Harada, Shuichiro Tao, Qiang Yin
We calculate the false-vacuum decay rate in one-dimensional quantum mechanics on the basis of the saddle-point approximation in the Euclidean path integral at finite temperature. T…
