Finite Temperature Theory of Metastable Anharmonic Potentials
Marco Zoli
The decay rate for a particle in a metastable cubic potential is investigated in the quantum regime by the Euclidean path integral method in semiclassical approximation. The imagin…
Metastability Driven by Soft Quantum Fluctuation Modes
Marco Zoli
The semiclassical Euclidean path integral method is applied to compute the low temperature quantum decay rate for a particle placed in the metastable minimum of a cubic potential i…
On the Decay Rate of the False Vacuum
Marco Zoli
The finite size theory of metastability in a quartic potential is developed by the semiclassical path integral method. In the quantum regime, the relation between temperature and c…
Instanton Solution of a Nonlinear Potential in Finite Size
Marco Zoli
The Euclidean path integral method is applied to a quantum tunneling model which accounts for finite size () effects. The general solution of the Euler Lagrange equation for the…
