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…
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…
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…
