Eccentricity valley Hall effect
Jin Cao, Shen Lai, Cong Xiao +2
Valleytronics harnesses the valley degree of freedom -- energy-degenerate extrema in the electronic band structure -- for information storage and processing. Valley Hall effect (VH…
Lorentz Skew Scattering Nonreciprocal Magneto-Transport
Xiu Fang Lu, Xue-Jin Zhang, Naizhou Wang +9
In materials with broken inversion symmetry, nonreciprocal magneto-transport (NRMT) manifests as a bilinear dependence of charge conductivity on applied electric (E) and magnetic (…
Tunable linear and nonlinear anomalous Hall transport in two-dimensional CrPS
Lulu Xiong, Jin Cao, Fan Yang +5
Few-layer CrPS is a two-dimensional (2D) magnetic material with excellent stability in ambient environment, which attracted significant interest in recent research. Here, via…
Intrinsic nonlinear valley Nernst effect
Xue-Jin Zhang, Jin Cao, Lulu Xiong +4
We investigate the intrinsic nonlinear valley Nernst effect, which induces a transverse valley current via a second-order thermoelectric response to a longitudinal temperature grad…
Nonlinear Néel Spin-Orbit Torque in Centrosymmetric Antiferromagnets
Jin Cao, Weikang Wu, Huiying Liu +4
Electric control of Néel vector is a central task of antiferromagnetic (AFM) spintronics. The major scheme so far relies on the linear Néel torque, which however is restricted to…
Theory of Nonlocal Transport from Nonlinear Valley Responses
Jin Cao, Hui Wang, Shen Lai +2
We develop a theory for the nonlocal measurement of nonlinear valley Hall effect. Different from the linear case where the direct and the inverse processes are reciprocal, we unvei…
