Unified Semiclassical Theory of Nonlinear Hall Effect:Bridging Ballistic and Diffusive Transport Regime
Xinyu Liu, Haozhi Liao, Guangyun Qi +3
The nonlinear Hall effect has attracted considerable attention and undergone extensive investigation in recent years. However, theoretical studies addressing size-dependent effects…
Nonreciprocal Ballistic Transport in Asymmetric Bands
Minhao Zou, Hao Geng, Rong Ma +3
Nonreciprocal transport in uniform systems has attracted great research interest recently and the existing theories mainly focus on the diffusive regime. In this study, we uncover…
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…
Kondo-induced hybrid topological insulator in two-dimensional electron system with a quadratic band crossing point
Rui Wang, Baigeng Wang, L. Sheng +2
We investigate the Kondo effect in the two-dimensional electron system with a non-trivial quadratic energy band crossing point. We show that the Kondo effect can induce a new hybri…
Detecting Majorana fermions by use of superconductor-quantum Hall liquid junctions
Zheng-Wei Zuo, Huijuan Li, Liben Li +3
The point contact tunnel junctions between a one-dimensional topological superconductor and single-channel quantum Hall (QH) liquids are investigated theoretically with bosonizatio…
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…
Majorana and fractionally charged bound states in 1-D Rashba nanowire under spatially varying Zeeman fields
Xiaoyu Zhu, Wei Chen, R. Shen +1
We study topological phase transitions in one dimensional (1-D) Rashba nanowire under a spatially varying Zeeman field when coupled to an -wave superconductor substrate. We show…
Specular Andreev Reflection in Inversion-symmetric Weyl-semimetals
Wei Chen, Liang Jiang, R. Shen +3
The electron-hole conversion at the normal-metal superconductor interface in inversion-symmetric Weyl semimetals is investigated with an effective two-band model. We find that the…
