Second-Order Topological Phases in Non-Hermitian Systems
Tao Liu, Yu-Ran Zhang, Qing Ai +4
A -dimensional second-order topological insulator (SOTI) can host topologically protected -dimensional gapless boundary modes. Here we show that a 2D non-Hermitian SOTI…

Topological unification of time-reversal and particle-hole symmetries in non-Hermitian physics
Kohei Kawabata, Sho Higashikawa, Zongping Gong +2
Topological phases are enriched in non-equilibrium open systems effectively described by non-Hermitian Hamiltonians. While several properties unique to non-Hermitian topological sy…

Topological phases of non-Hermitian systems
Zongping Gong, Yuto Ashida, Kohei Kawabata +3
Recent experimental advances in controlling dissipation have brought about unprecedented flexibility in engineering non-Hermitian Hamiltonians in open classical and quantum systems…
