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…
