Instantonic Methods for Quantum Tunneling in Finite Size
Marco Zoli
The instantonic approach for a model potential is reexamined in the asymptotic limit. The path integral of the system is derived in semiclassical approximation expanding the…

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…
