Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
Light-induced half-quantized Hall effect and axion insulator
Fang Qin, Ching Hua Lee, Rui Chen
Motivated by the recent experimental realization of the half-quantized Hall effect phase in a three-dimensional (3D) semi-magnetic topological insulator [M. Mogi et al., Nature Phy…
On the half-quantized Hall conductance of massive surface electrons in magnetic topological insulator films
Rui Chen, Shun-Qing Shen
In topological insulators, massive surface bands resulting from local symmetry breaking are believed to exhibit a half-quantized Hall conductance. However, such scenarios are obvio…
Chiral edge state coupling theory of transport in quantum anomalous Hall insulators
Rui Chen, Hai-Peng Sun, Bin Zhou +1
Theoretically, the quantum anomalous Hall effect is characterized by a quantized Hall conductance. However, many experiments only reported the quantization of the Hall resistance,…
Light-induced phase crossovers in a quantum spin Hall system
Fang Qin, Ching Hua Lee, Rui Chen
In this work, we theoretically investigate the light-induced topological phases and finite-size crossovers in a paradigmatic quantum spin Hall (QSH) system with high-frequency pump…
Controlled Ordering of Room-Temperature Magnetic Skyrmions in a Polar Van der Waals Magnet
Peter Meisenheimer, Hongrui Zhang, David Raftrey +10
Control and understanding of ensembles of skyrmions is important for realization of future technologies. In particular, the order-disorder transition associated with the 2D lattice…
Half-Quantized Hall Effect at the Parity-Invariant Fermi Surface
Jin-Yu Zou, Rui Chen, Bo Fu +3
Condensed matter realization of a single Dirac cone of fermions in two dimensions is a long-standing issue. Here we report the discovery of a single gapless Dirac cone of half-quan…
Higher-order topological insulators in hyperbolic lattices
Zheng-Rong Liu, Chun-Bo Hua, Tan Peng +2
To explore the non-Euclidean generalization of higher-order topological phenomena, we construct a higher-order topological insulator model in hyperbolic lattices by breaking the ti…
Density-driven higher-order topological phase transitions in amorphous solids
Tan Peng, Chun-Bo Hua, Rui Chen +3
Amorphous topological states, which are independent of the specific spatial distribution of microscopic constructions, have gained much attention. Recently, higher-order topologica…
Layer Hall effect induced by hidden Berry curvature in antiferromagnetic insulators
Rui Chen, Hai-Peng Sun, Mingqiang Gu +4
The layer Hall effect describes electrons spontaneously deflected to opposite sides at different layers, which has been experimentally reported in the MnBiTe thinfilms unde…
Double band inversion in the topological phase transition of Ge1-xSnx alloys
Rui Tan, Qirui Yang, Ruiyuan Chen +5
We use first-principles simulation and virtual crystal approximation to reveal the unique double band inversion and topological phase transition in Ge1-xSnx alloys. Wavefunction pa…
Magnetic field effects on the quantum spin liquid behaviors of NaYbS
Jiangtao Wu, Jianshu Li, Zheng Zhang +23
Spin-orbit coupling is an important ingredient to regulate the many-body physics, especially for many spin liquid candidate materials such as rare-earth magnets and Kitaev material…
