Momentum flatband and superluminal propagation in a photonic time Moiré superlattice
Linyang Zou, Hao Hu, Haotian Wu +4
Flat bands typically describe energy bands whose energy dispersion is entirely or almost entirely degenerate. One effective method to form flat bands is by constructing Moiré supe…

Versatile Braiding of Non-Hermitian Topological Edge States
Bofeng Zhu, Qiang Wang, You Wang +2
Among the most intriguing features of non-Hermitian (NH) systems is the ability of complex energies to form braids under parametric variation. Several braiding behaviors, including…
