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…
Charge density wave modulated third-order nonlinear Hall effect in 1-VSe nanosheets
Zhao-Hui Chen, Xin Liao, Jing-Wei Dong +5
We report the observation of a pronounced third-order nonlinear Hall effect (NLHE) in 1-phase VSe nanosheets, synthesized using chemical vapor deposition (CVD). The nanoshee…
Giant Third-Order Nonlinearity Induced by the Quantum Metric Quadrupole in Few-Layer WTe2
Xing-Yu Liu, An-Qi Wang, Dong Li +3
The quantum geometric properties of topological materials underpin many exotic physical phenomena and applications. Quantum nonlinearity has emerged as a powerful probe for reveali…
Nonlinear Valley and Spin Valves in Bilayer Graphene
Xin Liao, Xing-Yu Liu, An-Qi Wang +3
Nonlinear transport plays a vital role in probing the quantum geometry of Bloch electrons, valley chirality, and carrier scattering mechanisms. The nonlinear Hall effect, character…
Orbital anomalous Hall effect in the few-layer Weyl semimetal TaIrTe4
An-Qi Wang, Dong Li, Tong-Yang Zhao +7
We report on the observation of the linear anomalous Hall effect (AHE) in the nonmagnetic Weyl semimetal TaIrTe4. This is achieved by applying a direct current Idc and an alternati…
