Dual topological characterization of non-Hermitian Floquet phases
Non-Hermiticity is expected to add far more physical features to the already rich Floquet
topological phases of matter. Nevertheless, a systematic approach to characterize non …

Reservoir-assisted symmetry breaking and coalesced zero-energy modes in an open -symmetric Su-Schrieffer-Heeger model
S Garmon, K Noba - Physical Review A, 2021 - APS
We study a model consisting of a central PT-symmetric trimer with non-Hermitian strength
parameter γ coupled to two semi-infinite Su-Schrieffer-Heeger (SSH) leads. We show the …

A chain of solvable non-Hermitian Hamiltonians constructed by a series of metric operators
F Bagarello, N Hatano - Annals of Physics, 2021 - Elsevier
We show how, given a non-Hermitian Hamiltonian H, we can generate new non-Hermitian
operators sequentially, producing a virtually infinite chain of non-Hermitian Hamiltonians …
