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…
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…
The fate of reentrant localization phenomenon in the one-dimensional dimerized quasiperiodic chain with long-range hopping
Haoyu Wang, Xiaohong Zheng, Jun Chen +3
Recently, the exciting reentrant localization transition phenomenon was found in a one-dimensional dimerized lattice with staggered quasiperiodic potentials. Usually, long-range ho…
