Figure 3: Surface states and Fermi arcs.
From: Symmetry-protected ideal Weyl semimetal in HgTe-class materials
Electronic structure of HgTe with surfaces in the ideal Weyl semimetal phase. (a) Band structure projected onto the (001) surface BZ. The red lines denote the surface states. (b) Surface Fermi arcs in the (001) surface BZ form a closed loop, because each gapless point has the monopole charge of +2 or −2. (c) Band structure projected onto the (010) surface BZ. (d) Surface Fermi arcs in the (010) surface BZ. (e,f) To see Fermi arcs clearly, the Fermi surfaces around the Weyl nodes are zoomed in.
