An An exactly solvable PT symmetric potential from the Natanzon class
G. Levai, A. Sinha, P. Roy
The symmetric version of the generalised Ginocchio potential, a member of the general exactly solvable Natanzon potential class is analysed and its properties are compa…
PT-invariant one-dimensional Coulomb problem
Anjana Sinha, Rajkumar Roychoudhury
The one-dimensional Coulomb-like potential with a real coupling constant beta, and a centrifugal-like core of strength G = alpha^2 - {1/4}, viz. V(x) = {alpha^2 - (1/4)}/{(x-ic)^2}…
Energy spectra of two electrons in a circular quantum dot
Anjana Sinha, Y. P. Varshni
The electron interaction energy of two interacting electrons in a circular quantum dot (with hard wall confinement) is investigated in the framework of the semi-classical Wentzel-K…
Three Dimensional Confinement : WKB Revisited
Anjana Sinha
An alternate formalism is developed to determine the energy eigenvalues of quantum mechanical systems, confined within a rigid impenetrable spherical box of radius , in the fr…
