Observation of giant nonreciprocal charge transport from quantum Hall states in a topological insulator
Chunfeng Li, Rui Wang, Shuai Zhang +10
Symmetry breaking in quantum materials is of great importance and can lead to nonreciprocal charge transport. Topological insulators provide a unique platform to study nonreciproca…
Robustness of Half-Integer Quantized Hall Conductivity against Disorder in an Anisotropic Dirac Semimetal with Parity Anomaly
Zhen Ning, Xianyong Ding, Dong-Hui Xu +1
Two-dimensional Dirac semimetals with a single massless Dirac cone exhibit the parity anomaly. Usually, such a kind of anomalous topological semimetallic phase in real materials is…
Experimental observation of the gate-controlled reversal of the anomalous Hall effect in the intrinsic magnetic topological insulator MnBi2Te4 device
Shuai Zhang, Rui Wang, Xuepeng Wang +17
Here we report the reserved anomalous Hall effect (AHE) in the 5-septuple-layer van der Waals device of the intrinsic magnetic topological insulator MnBi2Te4. By employing the top/…
Phase transition and anomalous scaling in the quantum Hall transport of topological insulator Sn-Bi1.1Sb0.9Te2S devices
Faji Xie, Shuai Zhang, Qianqian Liu +12
The scaling physics of quantum Hall transport in optimized topological insulators with a plateau precision of ~1/1000 e2/h is considered. Two exponential scaling regimes are observ…
Emergence of excitonic superfluid at topological-insulator surfaces
Yasen Hou, Rui Wang, Rui Xiao +11
Excitons are spin integer particles that are predicted to condense into a coherent quantum state at sufficiently low temperature, and exciton condensates can be realized at much hi…
Stepwise quantized surface states and delayed Landau level hybridization in Co cluster-decorated BiSbTeSe2 topological insulator devices
Shuai Zhang, Li Pi, Rui Wang +16
In three-dimensional topological insulators (TIs), the nontrivial topology in their electronic bands casts a gapless state on their solid surfaces, using which dissipationless TI e…
Nontrivial Berry phase and type II Dirac transport in layered material PdTe2
Fucong Fei, Xiangyan Bo, Rui Wang +11
Here we report the evidence of the type II Dirac Fermion in the layered crystal PdTe2. The de Haas-van Alphen oscillations find a small Fermi pocket with a cross section of 0.077nm…
Universal anyons at the irradiated surface of topological insulator
Rui Wang, Wei Chen, Baigeng Wang +1
Anyons have recently received great attention due to their promising application in topological quantum computation. The best validated system that enjoys the anyonic excitations a…
Lateral Heterojunction Sb2Te3/Bi2Te3 and its topological transport
Fucong Fei, Qianjin Wang, Zhongxia Wei +9
A lateral heterojunction of topological insulator Sb2Te3/Bi2Te3 was successfully synthesized using a two-step solvothermal method. The two crystalline components were separated wel…
Mimicing the Kane-Mele type spin orbit interaction by spin-flexual phonon coupling in graphene devices
Zhanbin Bai, Rui Wang, Yazhou Zhou +12
On the efforts of enhancing the spin orbit interaction (SOI) of graphene for seeking the dissipationless quantum spin Hall devices, unique Kane-Mele type SOI and high mobility samp…
Floquet Weyl Semimetal Induced by Off-Resonant Light
Rui Wang, Baigeng Wang, Rui Shen +3
We propose that a Floquet Weyl semimetal state can be induced in three-dimensional topological insulators, either nonmagnetic or magnetic, by the application of off-resonant light.…
Entanglement, subsystem particle numbers and topology in free fermion systems
Y. F. Zhang, L. Sheng, R. Shen +2
We study the relationship between bipartite entanglement, subsystem particle number and topology in a half-filled free fermion system. It is proposed that the spin-projected partic…
