Identifying geometric third-order nonlinear transport in disordered materials
Zhen-Hao Gong, Zhi-Hao Wei, Hai-Zhou Lu +1
The paper presents a symmetry‑guided framework to separate quantum‑geometric and disorder‑mediated contributions to third‑order nonlinear transport in disordered materials, using m…
Scaling analysis of quantum geometry in second-order nonlinear transport
Zhen-Hao Gong, Z. Z. Du, Hai-Peng Sun +2
The paper derives a scaling law that separates quantum‑geometric contributions from disorder effects in the second‑order nonlinear Hall response, allowing experimental identificati…
Nonperturbative Magnetic Orbital Hall Effect in Altermagnets
Xukun Feng, Jin Cao, Lay Kee Ang +3
Recent studies on altermagnets have focused considerable attention on nonrelativistic effects that persist in the absence of spin-orbit coupling (SOC). As a result, the relative im…
Anisotropic Surface Spin Waves as Signature of A-type Altermagnets
Zhoujian Sun, Yiyuan Chen, Tao Yu +2
Altermagnets have attracted intense interest because they have the advantages of both ferromagnets and antiferromagnets. However, their experimental identification remains challeng…
3D Quantum Hall Effect with Two Distinct Plateaus
Jun-Hong Li, Yi-Yuan Chen, Peng-Lu Zhao +2
The recent discovery of the 3D quantum Hall effect in has also revealed puzzling signatures of possible 3D fractionalization. Beyond the first plateau associated…
Quantum Christoffel Nonlinear Magnetization
Xiao-Bin Qiang, Xiaoxiong Liu, Hai-Zhou Lu +1
The Christoffel symbol is an essential quantity in Einstein's general theory of relativity. We discover that an electric field can induce a nonlinear magnetization in quantum mater…
