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…
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…
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…
Nonlinear spin and orbital Edelstein effect in WTe2
Xing-Guo Ye, Peng-Fei Zhu, Wen-Zheng Xu +2
In materials with spin-momentum locked spin textures, such as Rashba states and topological surface states, the current-induced shift of the Fermi contour in the k space leads to s…
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…
