Scaling analysis of quantum geometry in second-order nonlinear transport
Zhen-Hao Gong, Z. Z. Du, Hai-Peng Sun +2
Quantum geometry encodes the structure of the Hilbert space of Bloch states and can be accessed through nonlinear transport. Yet, disorder-induced mechanisms generically contribute…
Nonlinear Hall effect on a disordered lattice
Rui Chen, Z. Z. Du, Hai-Peng Sun +2
The nonlinear Hall effect has recently attracted significant interest due to its potential as a promising spectral tool and device applications. A theory of the nonlinear Hall effe…
Absence of the anomalous Hall effect in planar Hall experiments
C. M. Wang, Z. Z. Du, Hai-Zhou Lu +1
Recently, the planar Hall effect has attracted tremendous interest. In particular, an in-plane magnetization can induce an anomalous planar Hall effect with a period for hex…
Topological and disorder corrections to the transverse Wiedemann-Franz law and Mott relation in kagome magnets
Xiao-Bin Qiang, Z. Z. Du, Hai-Zhou Lu +1
The Wiedemann-Franz law and Mott relation are textbook paradigms on the ratios of the thermal and thermoelectric conductivities to electrical conductivity, respectively. Deviations…
