Quantum third-order nonlinear Hall effect of a four-terminal device with time-reversal symmetry

Miaomiao Wei, Longjun Xiang, Luyang Wang +2

The third-order nonlinear Hall effect induced by Berry-connection polarizability tensor has been observed in Weyl semimetals T${}_d$-MoTe${}_2$ as well as T${}_d$-TaIrTe${}_4$. The experim…
