Extended Data Fig. 9: Linked Weyl loop Fermi surface.
From: Observation of a linked-loop quantum state in a topological magnet
Constant-energy slice of the pockets (navy) making up the linked Weyl loops obtained by ab initio calculation, at binding energy EB = −10 meV below the experimental Fermi level. Plotted a, in an extended zone scheme (only two loops shown for simplicity) and b, the reduced Brillouin zone (all three loops shown). The Fermi surface pockets touch at a set of discrete points, where the Weyl loop disperses through this particular EB. For reference, the full Weyl loop trajectories are indicated, collapsed in energy (magenta around X1, red around X2, orange around X3). The Weyl loop Fermi surface pockets form a linked structure.
