Emergence of exceptional points and their spectroscopic signature in Dirac semimetal-dirty Superconductor heterojunction

Sayan Jana, Debashree Chowdhury, Arijit Saha

We theoretically investigate the emergence of non-hermitian physics at the heterojunction of a type-II Dirac semi-metal (DSM) and a dirty superconductor (DSC). The non-hermiticity…
