Nonreciprocal Charge and Spin Transport Induced by Non-Hermitian Skin Effect in Mesoscopic Heterojunctions
H. Geng, J. Y. Wei, M. H. Zou +3
The pursuit of the non-Hermitian skin effect (NHSE) in various physical systems is of great research interest. Compared with recent progress in non-electronic systems, the implemen…
Sign reversal of magnetoresistivity in massive nodal-line semimetals due to Lifshitz transition of Fermi surface
Min-Xue Yang, Hao Geng, Wei Luo +3
Topological nodal-line semimetals offer an interesting research platform to explore novel phenomena associated with its torus-shaped Fermi surface. Here, we study magnetotransport…
Theoretical study for 3D quantum Hall effect in a periodic electron system
H. Geng, G. Y. Qi, L. Sheng +2
The exsitance of three-dimensional Hall effect (3DQHE) due to spontaneous Fermi surface instabilities in strong magnetic field was proposed decades ago, and has stimulated recent p…
Aharonov-Bohm Effect in Three-dimensional Higher-order Topological Insulator
Kun Luo, Hao Geng, Li Sheng +2
Hinge states are the hallmark of the 3D higher-order topological insulator(HOTI). Here, we show that chiral hinge states can be identified by the magnetic field induced Aharonov-Bo…
Random-gate-voltage induced Al'tshuler-Aronov-Spivak effect in topological edge states
Kun Luo, Wei Chen, Li Sheng +1
Helical edge states are the hallmark of the quantum spin Hall insulator. Recently, several experiments have observed transport signatures contributed by trivial edge states, making…
Three-dimensional quantum Hall effect and magnetothermoelectric properties in Weyl semimetals
R. Ma, D. N. Sheng, L. Sheng
We numerically study the three-dimensional (3D) quantum Hall effect (QHE) and magnetothermoelectric transport of Weyl semimetals in the presence of disorder. We obtain a bulk pictu…
