Gate-tunable anisotropic Josephson diode effect in topological Dirac semimetal CdAs nanowires
Yan-Liang Hou, An-Qi Wang, Na Li +4
The intrinsic Josephson diode effect (JDE) has recently attracted considerable attention due to its sensitivity to broken symmetries in Josephson junctions, offering a powerful pro…
Radio-Frequency Quantum Rectification in Kagome Superconductor CsV3Sb5
Han-Xin Lou, Jing-Jing Chen, Xing-Guo Ye +13
Rectification of electromagnetic fields into direct current (DC) is pivotal for energy harvesting, wireless charging, and next-generation communication technologies. The supercondu…
Magnetic Field Induced Quantum Metric Dipole in Dirac Semimetal Cd3As2
Tong-Yang Zhao, An-Qi Wang, Zhen-Tao Zhang +3
The quantum geometry, comprising Berry curvature and quantum metric, plays a fundamental role in governing electron transport phenomena in solids. Recent studies show that the quan…
From surface Fermi arcs to Fermi loops in the Dirac semimetal Cd3As2
An-Qi Wang, Tong-Yang Zhao, Chuan Li +3
Arc-like topological surface states, i.e., surface Fermi arcs, have long been recognized as the hallmark of Dirac semimetals. However, recent theories suggest that the surface Ferm…
Engineering nonlinear Hall effect in bilayer graphene/black phosphorus heterostructures
Xing-Guo Ye, Zhen-Tao Zhang, Peng-Fei Zhu +3
Two-dimensional van der Waals materials offer a highly tunable platform for generating emergent quantum phenomena through symmetry breaking. Stacking-induced symmetry breaking at i…
Nonlinear Valley and Spin Valves in Bilayer Graphene
Xin Liao, Xing-Yu Liu, An-Qi Wang +3
