Simple unified derivation and solution of Coulomb, Eckart and Rosen-Morse potentials in prepotential approach
Choon-Lin Ho
The four exactly-solvable models related to non-sinusoidal coordinates, namely, the Coulomb, Eckart, Rosen-Morse type I and II models are normally being treated separately, despite…
Self-Adjoint Extensions of the Hamiltonian Operator with Symmetric Potentials which are Unbounded from Below
Hing-Tong Cho, Choon-Lin Ho
We study the self-adjoint extensions of the Hamiltonian operator with symmetric potentials which go to faster than with as . In this exte…
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…
Quasi-exact Solvability of Planar Dirac Electron in Coulomb and Magnetic Fields
Chun-Ming Chiang, Choon-Lin Ho
The Dirac equation for an electron in two spatial dimensions in the Coulomb and homogeneous magnetic fields is a physical example of quasi-exactly solvable systems. This model, how…
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…
