Zero energy states of Dirac equation in -dimensional curved spacetime
Choon-Lin Ho, Pinaki Roy
We consider Dirac equation in dimensional curved spacetime in the presence of a scalar potential. It is then shown that the zero energy states are degenerate and they can b…

Quantum backflow of a Dirac fermion on a ring
Valentin Daniel Paccoia, Orlando Panella, Pinaki Roy
We study the quantum backflow problem of a relativistic charged Dirac fermion constrained to move on a ring of radius . Using the relativistic current operator we compute the pr…
