Abstract
We consider the Z2 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 similar to the real-space nexus, an analog of the Dirac monopole at which the Z2 strings terminate.Description
