Nexus and Dirac lines in topological materials
We consider the Z _2 topology of the Dirac lines, i.e., lines of band contacts, on an example of graphite. Four lines—three with topological charge ${N}_{1}=1$ each and one with ${N}_{1}=-1$ —merge together near the H-point and annihilate due to summation law $1+1+1-1=0$ . The merging point is simil...
