Stabilizing quantum metastable states in a time-periodic potential
Choon-Lin Ho, Chung-Chieh Lee
In this talk we present a model to demonstrate how time-periodic potential can be used to manipulate quantum metastability of a system. We study metastability of a particle trapped…
Quantum metastability in time-periodic potentials
Chung-Chieh Lee, Choon-Lin Ho
In this paper we investigate quantum metastability of a particle trapped in between an infinite wall and a square barrier, with either a time-periodically oscillating barrier (Mode…
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…
