Photonic chiral state transfer near the Liouvillian exceptional point
Huixia Gao, Konghao Sun, Dengke Qu +4
As branch-point singularities of non-Hermitian matrices, the exceptional points (EPs) exhibit unique spectral topology and criticality, with intriguing dynamic consequences in non-…
Observation of Braid-Protected Unpaired Exceptional Points
Kunkun Wang, J. Lukas K. König, Kang Yang +4
Spectral degeneracies (dubbed nodal points in momentum space) play fundamental roles in understanding exotic properties of light and matter. In lattice systems, unpaired band-struc…
Self acceleration from spectral geometry in dissipative quantum-walk dynamics
Peng Xue, Quan Lin, Kunkun Wang +3
Dynamic behaviors of a physical system often originate from its spectral properties. In open systems, where the effective non-Hermitian description enables a wealth of spectral str…
Observation of non-Hermitian edge burst in quantum dynamics
Lei Xiao, Wen-Tan Xue, Fei Song +4
The non-Hermitian skin effect, by which the eigenstates of Hamiltonian are predominantly localized at the boundary, has revealed a strong sensitivity of non-Hermitian systems to th…
Experimental Simulation of Symmetry-Protected Higher-Order Exceptional Points with Single Photons
Kunkun Wang, Lei Xiao, Haiqing Lin +3
Exceptional points (EPs) of non-Hermitian (NH) systems have recently attracted increasing attention due to their rich phenomenology and intriguing applications. Compared to the pre…
Simulating non-Hermitian quasicrystals with single-photon quantum walks
Quan Lin, Tianyu Li, Lei Xiao +3
Non-Hermiticity significantly enriches the properties of topological models, leading to exotic features such as the non-Hermitian skin effects and non-Bloch bulk-boundary correspon…
Observation of non-Hermitian topological Anderson insulator in quantum dynamics
Quan Lin, Tianyu Li, Lei Xiao +3
Disorder and non-Hermiticity dramatically impact the topological and localization properties of a quantum system, giving rise to intriguing quantum states of matter. The rich inter…
Detecting non-Bloch topological invariants in quantum dynamics
Kunkun Wang, Tianyu Li, Lei Xiao +3
Non-Bloch topological invariants preserve the bulk-boundary correspondence in non-Hermitian topological systems, and are a key concept in the contemporary study of non-Hermitian to…
Observation of non-Hermitian bulk-boundary correspondence in quantum dynamics
Lei Xiao, Tianshu Deng, Kunkun Wang +4
Bulk-boundary correspondence, a central principle in topological matter relating bulk topological invariants to edge states, breaks down in a generic class of non-Hermitian systems…
