Journal ArticleDOI
Non-Hermitian bulk-boundary correspondence in quantum dynamics
TL;DR: In this paper, the non-Hermitian bulk-boundary correspondence was shown to hold for a wide range of open topological systems with effective non-Bloch Hamiltonians.
Journal ArticleDOI
Observation of non-Hermitian bulk-boundary correspondence in quantum dynamics
TL;DR: In this paper, the authors theoretically predict and experimentally observe non-Hermitian bulk-boundary correspondence in discrete-time quantum-walk dynamics of single photons, and demonstrate photon localizations near boundaries even in the absence of topological edge states.
Journal ArticleDOI
Observation of Non-Bloch Parity-Time Symmetry and Exceptional Points.
TL;DR: In this article, a family of exceptional points in non-unitary quantum walks of single photons is discovered. But the exceptional points are not the same as the non-Bloch exceptional points, which inhabit a generalized Brillouin zone.
Journal ArticleDOI
Fixed Points and Dynamic Topological Phenomena in a Parity-Time-Symmetric Quantum Quench
TL;DR: It is proved the existence of fixed points for quenches between distinct static topological phases in the PT-symmetry-preserving regime, thus unveiling the interplay between dynamic topological phenomena and PT symmetry.
Journal ArticleDOI
Fixed points and emergent topological phenomena in a parity-time-symmetric quantum quench
TL;DR: In this paper, the authors identify emergent topological phenomena such as dynamic Chern numbers and dynamic quantum phase transitions in quantum quenches of the non-Hermitian Su-Schrieffer-Heeger Hamiltonian with parity-time symmetry.
