Topological flatband loop states in fractal-like photonic lattices
Limin Song, Yuqing Xie, Shiqi Xia +4
Noncontractible loop states (NLSs) are recently realized topological entity in flatband lattices, arising typically from band touching at a point where a flat band intersects one o…
Robustness versus sensitivity in non-Hermitian topological lattices probed by pseudospectra
I. Komis, D. Kaltsas, S. Xia +3
Non-Hermitian topological systems simultaneously posses two antagonistic features: ultra sensitivity due to exceptional points and robustness of topological zero energy modes, and…
Realization of second-order photonic square-root topological insulators
Wenchao Yan, Daohong Song, Shiqi Xia +4
Square-root higher-order topological insulators (HOTIs) are recently discovered new topological phases, with intriguing topological properties inherited from a parent lattice Hamil…
Nonlinear control of photonic higher-order topological bound states in the continuum
Zhichan Hu, Domenico Bongiovanni, Dario Jukić +7
Higher-order topological insulators (HOTIs) are recently discovered topological phases, possessing symmetry-protected corner states with fractional charges. An unexpected connectio…
Topological phenomena demonstrated in photorefractive photonic lattices
Shiqi Xia, Daohong Song, Nan Wang +5
Topological photonics has attracted widespread research attention in the past decade due to its fundamental interest and unique manner in controlling light propagation for advanced…
Valley-dependent wavepacket self-rotation and Zitterbewegung in symmetry-broken honeycomb lattices
Xiuying Liu, Frane Lunić, Daohong Song +6
The toolbox quantities used for manipulating the flow of light include typically amplitude, phase, and polarization. Pseudospins, such as those arising from valley degrees of freed…
