Perturbed Poeschl-Teller oscillators

, 2000
Wave functions and energies are constructed in a short-range Poeschl-Teller well (= negative quadratic secans hyperbolicus) with a quartic perturbation. Within the framework of an innovated, Lanczos-inspired perturbation theory we show that our choice of

A class of singular logarithmic potentials in a box with variety of skin thickness and wall interaction

, 2010
We obtain an analytic solution for a three-parameter class of logarithmic potentials at zero energy. The potential terms are products of the inverse square and the inverse log to powers 2, 1 and 0.

Analytical expression for the convolution of a Fano line profile with a Gaussian

, 2018
Asymmetric Fano line profiles are frequently encountered, e.g., in the photoionization spectra of atoms and ions. For the fitting of spectral line profiles to experimental spectra the line profiles have to be convolved with the experimental window ...

Polynomial Solutions of Shcrodinger Equation with the Generalized Woods Saxon Potential

, 2004
The bound state energy eigenvalues and the corresponding eigenfunctions of the generalized Woods Saxon potential are obtained in terms of the Jacobi polynomials. Nikiforov Uvarov method is used in the calculations.

Bohr-Sommerfeld quantization of spin Hamiltonians

, 2003
The Bohr-Sommerfeld rule for a spin system is obtained, including the first quantum corrections. The rule applies to both integer and half-integer spin, and respects Kramers degeneracy for time-reversal invariant systems. It is tested for various models,

Supersymmetry Across Nanoscale Heterojunction

, 2010
We argue that supersymmetric transformation could be applied across the heterojunction formed by joining of two mixed semiconductors. A general framework is described by specifying the structure of ladder operators at the junction for making quantitative

On the bound-state spectrum of a nonrelativistic particle in the background of a short-ranged linear potential

, 2010
The nonrelativistic problem of a particle immersed in a triangular potential well, set forth by N.A. Rao and B.A. Kagali, is revised. It is shown that these researchers misunderstood the full meaning of the potential and obtained a wrong quantization ...
