Unsupervised learning of non-Abelian multi-gap topological phases
Xiangxu He, Ruo-Yang Zhang, Xiaohan Cui +2
Recent experiments have successfully realized multi-band non-Abelian topological insulators with parity-time symmetry. Their topological classification transcends the conventional…
Light-induced thermal noise \textit{anomaly} governed by quantum metric
Longjun Xiang, Lei Zhang, Jun Chen +3
Traditionally, thermal noise in electric currents, arising from thermal agitation, is expected to increase with temperature and disappear as approaches zero. Contrary to th…
Band alignment effect in the topological photonic alloy
Tiantao Qu, Mudi Wang, Jun Chen +1
Recently, a photonic alloy with non-trivial topological properties has been proposed, based on the random mixing of Yttrium Iron Garnet (YIG) and magnetized YIG rods. When the dopi…
Electric field controlled valley-polarized photocurrent switch based on the circular bulk photovoltaic effect
Yaqing Yang, Xiaoyu Cheng, Liantuan Xiao +4
Efficient electric manipulation of valley degrees of freedom is critical and challenging for the advancement of valley-based information science and technology. We put forth an ele…
Topological photonic alloy
Tiantao Qu, Mudi Wang, Xiaoyu Cheng +6
We present the new concept of photonic alloy as a non-periodic topological material. By mixing non-magnetized and magnetized rods in a non-periodic 2D photonic crystal configuratio…
Unified framework of the microscopic Landau-Lifshitz-Gilbert equation and its application to Skyrmion dynamics
Fuming Xu, Gaoyang Li, Jian Chen +4
The Landau-Lifshitz-Gilbert (LLG) equation is widely used to describe magnetization dynamics. We develop a unified framework of the microscopic LLG equation based on the nonequilib…
Topological Anderson amorphous insulator
Xiaoyu Cheng, Tiantao Qu, Liantuan Xiao +3
The topological phase in amorphous systems adds a new dimension to the topological states of matter. Here, we present an interesting phenomenon dubbed the topological Anderson amor…
Gapless superconducting state and mirage gap in altermagnets
Miaomiao Wei, Longjun Xiang, Fuming Xu +3
The interplay between spin-orbit interaction (SOI) and magnetism produces interesting phenomena in superconductors. When a two-dimensional (2D) system with strong SOI is coupled to…
Observation of boundary induced chiral anomaly bulk states and their transport properties
Mudi Wang, Qiyun Ma, Shan Liu +5
The robust transport of edge modes is perhaps the most useful property of topological materials. The existence of edge modes is guaranteed by the bulk-edge correspondence, which st…
Topological one-way large-area waveguide states in magnetic photonic crystals
Mudi Wang, Ruo-Yang Zhang, Lei Zhang +4
We have theoretically and experimentally achieved large-area one-way transport by using heterostructures consisting of a domain of an ordinary photonic crystal (PC) sandwiched betw…
Experimental observation of non-Abelian topological charges and bulk-edge correspondence
Qinghua Guo, Tianshu Jiang, Ruo-Yang Zhang +5
In the past decades, topological concepts have emerged to classify matter states beyond the Ginzburg-Landau symmetry breaking paradigm. The underlying global invariants are usually…
All-Electrical Generation of Spin-Polarized Currents in Quantum Spin Hall Insulators
L. L. Tao, K. T. Cheung, L. Zhang +1
The control and generation of spin-polarized currents (SPCs) without magnetic materials and external magnetic field is a big challenge in spintronics and normally requires spin-fli…
