Quantum metastability in a class of moving potentials
Chung-Chieh Lee, Choon-Lin Ho
In this paper we consider quantum metastability in a class of moving potentials introduced by Berry and Klein. Potential in this class has its height and width scaled in a specific…

Stabilizing quantum metastable states in a time-periodic potential
Choon-Lin Ho, Chung-Chieh Lee
Metastability of a particle trapped in a well with a time-periodically oscillating barrier is studied in the Floquet formalism. It is shown that the oscillating barrier causes the…
