Exceptional-point-constrained locking of boundary-sensitive topological transitions in chiral non-Hermitian SSH-type lattices
Huimin Wang, Yanxin Liu, Zhijian Li +1
Topological transitions in non-Hermitian systems are generally boundary sensitive: a point-gap winding transition under periodic boundary condition (PBC) and a non-Bloch bulk real-…

Topological Phase Transitions and Edge-State Transfer in Time-Multiplexed Quantum Walks
Huimin Wang, Zhihao Xu, Zhijian Li
We investigate the topological phase transitions and edge-state properties of a time-multiplexed nonunitary quantum walk with sublattice symmetry. By constructing a Floquet operato…

Spatiotemporal Topological Combs for Robust High-Dimensional Information Transmission
Dawei Liu, Daijun Luo, Huiming Wang +8
Sculpting light across its independent degrees of freedom-from orbital angular momentum to the discrete wavelengths of optical frequency combs-has unlocked vast communication bandw…
