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…

Secure quantum conversation through non-destructive discrimination of highly entangled multipartite states
Sakshi Jain, Sreraman Muralidharan, Prasanta K. Panigrahi
"Quantum conversation" is a way in which two parties can communicate classical information with each other using entanglement as a shared resource. We present this scheme using a m…

Sub-Planck scale structures in the P{ö}schl-Teller potential and their sensitivity to perturbations
Utpal Roy, Suranjana Ghosh, P. K. Panigrahi +1
We find the existence of sub-Planck scale structures in the P{ö}schl-Teller potential, which is an exactly solvable potential with both symmetric and asymmetric features. We analyz…
