Antichiral hinge states in a higher-order photonic nodal ring semimetal
Yuchen Peng, Deep Mondal, Yuting Yang +17
Antichiral states propagate in the same direction on opposite boundaries, defying the conventional constraint that boundary modes must cancel net chirality. Previously found antich…

Symmetry-protected higher-order exceptional points in staggered flatband rhombic lattices
Yingying Zhang, Shiqiang Xia, Xingdong Zhao +9
Higher-order exceptional points (EPs), which appear as multifold degeneracies in the spectra of non-Hermitian systems, are garnering extensive attention in various multidisciplinar…
