Simulating Floquet non-Abelian topological insulator with photonic quantum walks
Quan Lin, Tianyu Li, Haiping Hu +2
Floquet non-Abelian topological phases emerge in periodically driven systems and exhibit properties that are absent in their Abelian or static counterparts. Dubbed the Floquet non-…
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…
