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…
Entanglement of Nambu Spinors and Bell Inequality Test Without Beam Splitters
Wei Luo, Hao Geng, D. Y. Xing +2
The identification of electronic entanglement in solids remains elusive so far, which is owed to the difficulty of implementing spinor-selective beam splitters with tunable polariz…
Cyclotron quantization and mirror-time transition on nonreciprocal lattices
Kai Shao, Zhuo-Ting Cai, Hao Geng +2
Unidirectional transport and localized cyclotron motion are two opposite physical phenomena. Here, we study the interplay effects between them on nonreciprocal lattices subject to…
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…
Inverse Edelstein effect of the surface states of a topological insulator
Hao Geng, Wei Luo, W. Y. Deng +3
The surface states of three-dimensional topological insulators posses the unique property of spin-momentum interlocking. This property gives rise to the interesting inverse Edelste…
Robust AC Quantum Spin Hall Effect without Participation of Edge States
W. Y. Deng, H. Geng, Wei Luo +4
The quantum spin Hall (QSH) effect in the DC regime, which has been intensively researched, relies on the existence of symmetry-protected edge states. Here, we demonstrate that a Q…
Effect of the edge states on the conductance and thermopower in Zigzag Phosphorene Nanoribbons
R. Ma, H. Geng, W. Y. Deng +3
We numerically study the effect of the edge states on the conductance and thermopower in zigzag phosphorene nanoribbons (ZPNRs) based on the tight-binding model and the scattering-…
Unified Theoretical Approach to Electronic Transport from Diffusive to Ballistic Regimes
H. Geng, W. Y. Deng, Y. J. Ren +2
We show that by integrating out the electric field and incorporating proper boundary conditions, a semiclassical Boltzmann equation can describe electron transport properties, cont…
Non-adiabatic topological spin pumping
W. Y. Deng, W. Luo, H. Geng +3
Based on the Floquet scattering theory, we analytically investigate the topological spin pumping for an exactly solvable model. Floquet spin Chern numbers are introduced to charact…
