Non-Hermitian phase-biased Josephson junctions
Jorge Cayao, Masatoshi Sato
We study non-Hermitian Josephson junctions formed by superconductors with a finite phase difference under non-Hermiticity, which naturally appears due to coupling to normal reservo…

Universal platform of point-gap topological phases from topological materials
Daichi Nakamura, Kazuya Inaka, Nobuyuki Okuma +1
Whereas point-gap topological phases are responsible for exceptional phenomena intrinsic to non-Hermitian systems, their realization in quantum materials is still elusive. Here we…
