Lifshitz-Kosevich Theory of Anomalous Landau Levels in Topological Flat Bands
Chao-Xing Liu
In conventional metals, quantum oscillations arise from Landau quantization of Fermi-surface cyclotron orbits, whose dynamics are governed by the Fermi velocity and cyclotron effec…
Imaging Surface Magnetization in Altermagnetic MnTe Films
Ling-Jie Zhou, Senlei Li, Zi-Jie Yan +13
Altermagnets with pronounced spin-splitting band structure, unconventional magnetic and crystal symmetries, and exotic magneto-transport properties have received immense interest i…
Boundary-Bulk Interplay in Nonlinear Topological Transport
Deyi Zhuo, Xiaoda Liu, Huu-Thong Le +7
Nonlinear transport has emerged as a powerful approach to probe the quantum geometry of electronic wavefunctions, such as Berry curvature and quantum metric, in topological materia…
Orbital Hybridization-Induced Ising-Type Superconductivity in a Confined Gallium Layer
Hemian Yi, Yunzhe Liu, Chengye Dong +24
In low-dimensional superconductors, the interplay between quantum confinement and interfacial hybridization effects can reshape Cooper pair wavefunctions and induce novel forms of…
Gate-Tunable Ambipolar Josephson Current in a Topological Insulator
Bomin Zhang, Xiaoda Liu, Junjie Qi +9
Dirac surface states in a topological insulator (TI) with proximity-induced superconductivity offer a promising platform for realizing topological superconductivity and Majorana ph…
Interlayer Coupling-Induced Quantum Phase Transition in Quantum Anomalous Hall Multilayers
Ling-Jie Zhou, Deyi Zhuo, Ruobing Mei +8
A quantum phase transition arises from competition between different ground states and is typically accessed by varying a single physical parameter near absolute zero temperature.…
