Selective Manipulation and Tunneling Spectroscopy of Broken-Symmetry Quantum Hall States in a Hybrid-edge Quantum Point Contact
Wei Ren, Xi Zhang, Jaden Ma +4
We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of e…
Axion Insulator State in Hundred-Nanometer-Thick Magnetic Topological Insulator Sandwich Heterostructures
Deyi Zhuo, Zi-Jie Yan, Zi-Ting Sun +10
An axion insulator is a three-dimensional (3D) topological insulator (TI), in which the bulk maintains the time-reversal symmetry or inversion symmetry but the surface states are g…
A Self-Adaptive First-Principles Approach for Magnetic Excited States
Zefeng Cai, Ke Wang, Yong Xu +2
The profound impact of excited magnetic states on the intricate interplay between electron and lattice behaviors in magnetic materials is a topic of great interest. Unfortunately,…
Long-Range Superconducting Proximity Effect in Nickel Nanowires
Jue Jiang, Weiwei Zhao, Fei Wang +6
When a ferromagnet is placed in contact with a superconductor, owing to incompatible spin order, the Cooper pairs from the superconductor cannot survive more than one or two nanome…
Even-Odd Layer-Dependent Anomalous Hall Effect in Topological Magnet MnBi2Te4 Thin Films
Yi-Fan Zhao, Ling-Jie Zhou, Fei Wang +10
A central theme in condensed matter physics is to create and understand the exotic states of matter by incorporating magnetism into topological materials. One prime example is the…
Gate-tunable Veselago Interference in a Bipolar Graphene Microcavity
Xi Zhang*, Wei Ren*, Elliot Bell +6
The relativistic charge carriers in monolayer graphene can be manipulated in manners akin to conventional optics (electron-optics): angle-dependent Klein tunneling collimates an el…
