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…
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…
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…
