Semimetals without correspondence between the topological charge of nodal line/surface and Fermi arc
Xue-Min Yang, Jiang-Shan Chen, Ying Chen +2
It is generally believed that there is a correspondence between the topological charge of nodal points or lines and the presence of Fermi arcs. Using a -inv…

Floquet topological phases with time-reversal and space inversion symmetries and dynamical detection of topological charges
Hong Wu, Yu-Chen Dong, Hui Liu
For spinful systems with spin 1/2, it is generally believed that P and T invariant strong and second-order topologies exist in four band and eight band system, respectively. Here,…
