Intrinsic nonlinear Hall effect in two-dimensional honeycomb topological antiferromagnets
Zheng-Yang Zhuang, Zhongbo Yan
Two-dimensional systems with honeycomb lattice are known to be a paradigmatic platform to explore the various types of Hall effects, owing to that the interplay of lattice geometry…
