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…
Reciprocity in parity violating non-Hermitian systems
Ananya Ghatak, Brijesh Kumar Mourya, Raka Dona Ray Mandal +1
Reciprocity is shown so far only when the scattering potential is either real or parity symmetric complex. We extend this result for parity violating complex potential by consideri…
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…
