High chern number two dimensional materials
WebThe observed high-Chern-number and high-temperature Chern insulator states require applying weak magnetic field due to the antiferromagnetic nature of MnBi2Te4 at zero magnetic field. As the ordinary QHE can also give rise to quantized Hall resistance plateau and vanishing longitudinal resistance, it is necessary to exclude the influence of Landau … http://albi3ro.github.io/M4/QAHE.html

The black circles mark B = 1 T and B = 9 T where Δ reaches about … WebThe fact that the Chern number Q is defined via the gauge invariant Berry fluxes ensures that Q itself is gauge invariant. Furthermore, taking the arg of Eq.(2.12) proves that the Chern numberQ is an integer. It is worthwhile to look a little deeper into the discrete formula for the Chern number. We can define modified Berry fluxesFQ nm as FQ
