Superconducting triode effect in a quantum-dot Josephson junction with a biased top gate
Yu-Hang Li, Xiaan Du, Hua Jiang +1
Non-reciprocal supercurrents enable non-dissipative rectification, holding great promise for superconducting electronics. Conventionally, this non-reciprocity, termed the supercond…
Electron Dynamics Reconstruction and Nontrivial Transport by Acoustic Waves
Zi-Qian Zhou, Zhi-Fan Zhang, Cong Xiao +2
Surface acoustic waves (SAWs) become a popular driving source in modern condensed matter physics, but most existing theories simplify them as electric fields and ignore the non-uni…
Three-dimensional quantum anomalous Hall effect in Weyl semimetals
Zhi-Qiang Zhang, Yu-Hang Li, Ming Lu +4
The quantum anomalous Hall effect (QAHE) is a quantum phenomenon in which a two-dimensional system exhibits a quantized Hall resistance in the absence of magnetic field, wh…
Domain Wall Engineering in Graphene-Based Josephson Junctions
Xia'an Du, Junjie Qi, Hua Jiang +1
Recent progress has enabled the controlled fabrication of domain walls (DWs) in graphene, which host topological kink states. Meanwhile, reliable techniques for constructing graphe…
Quantum kinetic theory of the semiclassical side jump, skew scattering and longitudinal velocity
Da Ma, Zhi-Fan Zhang, Hua Jiang +1
The semiclassical Boltzmann equation is widely used to study transport effects. However, being semiclassical and borrowing heavily from classical mechanics, the formalism calls for…
Quantized Topological States and Parity Anomaly in Intrinsic Quantum Anomalous Hall Insulator MnBi2Te4
Zhongxun Guo, Jingjing Gao, Zhiwei Huang +22
When thinned down to just a few atomic layers, the layered magnetic topological insulator MnBi2Te4 offers an exceptional platform for exploring a wide range of topological phenomen…
