A black potential for spin less particles
Ananya Ghatak, Mohammad Hasan, Bhabani Prasad Mandal
We consider the most general non-Hermitian Hulthen potential to study the scattering of spin-less relativistic particles. The conditions for CC, SS and CPA are obtained analyticall…

Critical coupling and coherent perfect absorption for ranges of energies due to a complex gain and loss symmetric system
Mohammad Hasan, Ananya Ghatak, Bhabani Prasad Mandal
We consider a non-Hermitian medium with a gain and loss symmetric, exponentially damped potential distribution to demonstrate different scattering features analytically. The condit…
