On the charge and magnetic ordering in monolayer NbSe: a first principles study
Feipeng Zheng, Zhimou Zhou, Xiaoqiang Liu +1
Monolayer NbSe has recently been shown to be a 2-dimensional superconductor, with a competing charge-density wave (CDW) order. This work investigates the electronic structure o…
Magnetoconductivity of type-II Weyl semimetals
Yi-Wen Wei, Chao-Kai Li, Jingshan Qi +1
Type-II Weyl semimetals are characterized by the tilted linear dispersion in the low-energy excitations, mimicking Weyl fermions but with manifest violation of the Lorentz invarian…
