Synthetic SU(1,1) Gauge Control of Non-Hermitian Light
Wanyue Xiao, Ruo-Yang Zhang, Yuqiong Cheng +1
Synthetic gauge fields enable nontrivial light control but remain largely restricted to compact groups such as U(1) and SU(2). Here, we study paraxial light propagation under a non…

Dynamic twisting and imaging of moiré crystals
Qixuan Zhang, Lingyuan Lyu, Sneh Pancholi +11
Moiré superlattices in stacked 2D crystals are powerful platforms for engineering correlated and topological quantum phases, with twisted graphene and transition metal dichalcogeni…

Edge and corner states in 2D non-Abelian topological insulators from an eigenvector frame rotation perspective
Tianshu Jiang, Ruo-Yang Zhang, Qinghua Guo +2
We propose the concept of 2D non-Abelian topological insulator which can explain the energy distributions of the edge states and corner states in systems with parity-time symmetry.…
