Isospectral potentials with Dirac delta interaction: Constrained Spectra

Kumar Abhinav, Biswanath Rath, Prasanta K. Panigrahi

We study quantum potentials containing Dirac delta function (DDF) within its supersymmetric (isospectral) construction via a discontinuous superpotential, instead of being simply a…

A study of PT-symmetric Non-linear Schroedinger Equation

K. Nireekshan Reddy, Subhrajit Modak, Kumar Abhinav +1

Systems governed by the Non-linear Schroedinger Equation (NLSE) with various external PT-symmetric potentials are considered. Exact solutions have been obtained for the same throug…

Conserved Correlation in PT -symmetric Systems: Scattering and Bound States

Kumar Abhinav, Arun Jayannavar, P. K. Panigrahi

For one-dimensional PT -symmetric systems, it is observed that the non-local product obtained from the continuity equation can be interpreted as a conserved corre- lation function.…

Supersymmetry and PT-Symmetric Spectral Bifurcation

Kumar Abhinav, Prasanta K. Panigrahi

Dynamical systems exhibiting both PT and Supersymmetry are analyzed in a general scenario. It is found that, in an appropriate parameter domain, the ground state may or may not res…

Comment on "Comment on 'Supersymmetry, PT-symmetry and spectral bifurcation'"

Kumar Abhinav, Prasanta K. Panigrahi

In "Comment on Supersymmetry, PT-symmetry and spectral bifurcation" \cite{BQ1}, Bagchi and Quesne correctly show the presence of a class of states for the complex Scarf-II potentia…

Supersymmetry, PT-symmetry and Spectral Bifurcation

Kumar Abhinav, Prasanta K. Panigrahi

We demonstrate that large class of PT-symmetric complex potentials, which can have isospectral real partner potentials, possess two different superpotentials. In the parameter doma…
