Scattering-Induced Magnon Layer-Hall Transport beyond Band Geometry
Zhiping Xue, Zhoujian Sun, Xiyin Ye +2
The layer Hall effect has been exclusively attributed to layer-locked Berry curvature, posing a fundamental barrier to its realization in conventional magnets. Here we report a fun…
Time-Reversal Invariant Topological Photonic Alloy
Feng Ruili, Qu Tiantao, Wu Xianbin +4
Conventional approaches generate quantum spin Hall (QSH) and quantum valley Hall (QVH) effects by breaking spatial inversion symmetry across the entire photonic crystal. Consequent…
Fragility of Unidirectional Transport in Weakly Disordered Photonic Chern Insulators
Xiaoxuan Shi, Tiantao Qu, Xianbin Wu +3
Photonic Chern insulators enable unidirectional light transport protected by nontrivial band topology -- essential for robust photonic integrated circuits and error-free communicat…
Magnetic doping-induced second-order and first-order topological phase transition inthe photonic alloy
Xianbin Wu, Tiantao Qu, Xiaoxuan Shi +2
The bulk-edge correspondence principle, a cornerstone of topological physics, ensures that first-order topological systems host robust chiral edge states in two dimension. This was…
Stochasticity-induced non-Hermitian skin criticality
Xiaoyu Cheng, Hui Jiang, Jun Chen +3
Typically, scaling up the size of a system does not change the shape of its energy spectrum, other than making it denser. Exceptions, however, occur in the new phenomenon of non-He…
Electric-field control of pure spin photocurrent in germanene
Yaqing Yang, Zhen Zhang, Liwen Zhang +4
The electrical control of pure spin current remains a central challenge in spintronics, particularly in time-reversal symmetric systems composed of nonmagnetic elements, where spin…
Disorder-driven exceptional points and concurrent topological phase transitions in non-Hermitian systems
Xiaoyu Cheng, Tiantao Qu, Yaqing Yang +2
Exceptional points (EPs) are spectral degeneracies unique to non-Hermitian systems which underpin phenomena from enhanced sensing to unconventional topology. While disorder is usua…
