Nonlinear Hall quantum oscillations to probe topological Brown-Zak fermions in graphene moiré systems
Jinrui Zhong, Huimin Peng, Yuqing Hu +7
Due to the deep connection with the quantum geometry of electronic Bloch wavefunctions, the second-order nonlinear Hall effect (NLHE) has been an attractive topic since its proposa…
