Fu–Kane–Mele monopoles in semimetals

In semimetals with time-reversal symmetry, the interplay between Weyl points and Fu–Kane–Mele indices results in coexisting surface Dirac cones and Fermi arcs that are transmutable without a topological phase transition. We show that Weyl points act as a new type of monopole, and that their connecti...
