Symmetry-enforced third-order nonlinear thermal Hall effects in altermagnets
Yun-Mei Li, Jiacheng Yao, Hua Wang +1
Thermal Hall effect (THE) is a powerful probe of material properties, even in insulators. Here we investigate the thermal response of altermagnets by developing a theory on Berry c…

Imaging the Néel Vector in Two-Dimensional Antiferromagnets using Antisymmetric Compton Scattering
Wuxuan Li, Zhuocheng Lu, Jingshan Qi +2
We demonstrate that antisymmetric Compton scattering can detect both the switching and the continuous rotation of the Néel vector in two-dimensional (2D) antiferromagnets. By probi…
