Characteristic influence of exceptional points in quantum dynamics
Savannah Garmon, Takafumi Sawada, Kenichi Noba +1
We review some recent work on the occurrence of coalescing eigenstates at exceptional points in non-Hermitian systems and their influence on physical quantities. We particularly fo…

Reservoir-assisted symmetry breaking and coalesced zero-energy modes in an open PT-symmetric Su-Schrieffer-Heeger model
Savannah Garmon, Kenichi Noba
We study a model consisting of a central -symmetric trimer with non-Hermitian strength parameter coupled to two semi-infinite Su-Schrieffer-Heeger (SSH) leads. We…
