The second-order intrinsic Wiedemann-Franz law
Ying-Fei Zhang, Zhi-Fan Zhang, Zhen-Gang Zhu +1
In recent years, the nonlinear anomalous thermal Hall effect has attracted substantial attention. In this paper, we carry out a theoretical exploration of the intrinsic anomalous t…
Intrinsic Second Order Spin Current
Zhi-Fan Zhang, Zhen-Gang Zhu, Gang Su
In recent years, nonlinear Hall effect has attracted great attention with three different terms contributed by Drude effect, Berry curvature dipole and Berry connection polarizabil…
Effect of disorder on Berry curvature and quantum metric in two-band gapped graphene
Ze Liu, Zhi-Fan Zhang, Zhen-Gang Zhu +1
The geometric properties of parameter space are mostly described by Berry curvature and quantum metric, which are the imaginary and real part of quantum geometric tensor, respectiv…
An intrinsic nonlinear Ohmic current
YuanDong Wang, ZhiFan Zhang, Zhen-Gang Zhu +1
It is known that intrinsic currents in magnetic metals often appear in the direction perpendicular to the external field for linear and nonlinear responses. Distinct from three kin…
