A review on non-Hermitian skin effect
Xiujuan Zhang, Tian Zhang, Ming-Hui Lu +1
The past decades have witnessed the flourishing of non-Hermitian physics in non-conservative systems, leading to unprecedented phenomena of unidirectional invisibility, enhanced se…
1550 nm compatible ultrafast photoconductive material based on a GaAs/ErAs/GaAs heterostructure
Kedong Zhang, Yiwen Li, Yifeng Ren +8
The sub-bandgap absorption and ultrafast relaxation in a GaAs/ErAs/GaAs heterostructure are reported. The infrared absorption and 1550 nm-excited ultrafast photo-response are studi…
Observation of higher-order non-Hermitian skin effect
Xiujuan Zhang, Yuan Tian, Jian-Hua Jiang +2
Hermitian theories play a major role in understanding the physics of most phenomena. It has been found only in the past decade that non-Hermiticity enables unprecedented effects su…
Large magnetoresistance observed in α-Sn/InSb heterostructures
Yuanfeng Ding, Huanhuan Song, Junwei Huang +7
In this study, we report the epitaxial growth of a series of α-Sn films on InSb substrate by molecular beam epitaxy (MBE) with thickness varying from 10 nm to 400 nm. High qualitie…
Corner states and topological transitions in two-dimensional higher-order topological sonic crystals with inversion symmetry
Zhan Xiong, Zhi-Kang Lin, Hai-Xiao Wang +4
Macroscopic two-dimensional sonic crystals with inversion symmetry are studied to reveal higher-order topological physics in classical wave systems. By tuning a single geometry par…
Higher-order Quantum Spin Hall Effect of Light
Biye Xie, Guangxu Su, Hong-Fei Wang +7
Band topology and related spin (or pseudo-spin) physics of photons provide us with a new dimension for manipulating light, which is potentially useful for information communication…
