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…

Heisenberg Symmetry and Collective Modes of One Dimensional Unitary Correlated Fermions
Kumar Abhinav, Chandrasekhar Bhamidipati, Vivek M Vyas +1
The correlated fermionic many-particle system, near infinite scattering length, reveals an underlying Heisenberg symmetry in one dimension, as compared to an symmetry in…
