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…

Enhancement of Josephson Supercurrent in a -Junction state by Chiral Antiferromagnetism
Jin-Xing Hou, Hai-Peng Sun, Björn Trauzettel +1
Magnetic order typically disrupts superconductivity, reducing the supercurrent. Here, we show that chiral antiferromagnetism, with non-relativistic spin-split bands and distinctive…

Tunable second harmornic in altermagnetic Josephson junctions
Hai-Peng Sun, Song-Bo Zhang, Chang-An Li +1
We study the influence of external electric and Zeeman fields on the Josephson effect in a planar superconductor/altermagnet/superconductor junction. Remarkably, we find that the c…
