Quasi-exactly solvable quasinormal modes
Choon-Lin Ho, Hing-Tong Cho
We consider quasinormal modes with complex energies from the point of view of the theory of quasi-exactly solvable (QES) models. We demonstrate that it is possible to find new pote…
Quasi-exact Solvability of Dirac Equations
Choon-Lin Ho
We present a general procedure for determining quasi-exact solvability of the Dirac and the Pauli equation with an underlying symmetry. This procedure makes full use of the…
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…
Fermion pair production in planar Coulomb and Aharonov--Bohm potentials
V. R. Khalilov, Choon-Lin Ho
Exact analytic solutions are found for the Dirac equation in 2+1 dimensions for a spin-one-half particle in a combination of the Lorentz 3-vector and scalar Coulomb as well as Ahar…
Scattering of spin-polarized electron in an Aharonov--Bohm potential
V. R. Khalilov, Choon-Lin Ho
The scattering of spin-polarized electrons in an Aharonov--Bohm vector potential is considered. We solve the Pauli equation in 3+1 dimensions taking into account explicitly the int…
A perturbative approach to a class of Fokker-Planck equations
Choon-Lin Ho, Yan-Min Dai
In this paper we present a direct perturbative method to solving certain Fokker-Planck equations, which have constant diffusion coefficients and some small parameters in the drift…
