Extended Data Fig. 3: Energy dispersion of the Weyl loop.
From: Observation of a linked-loop quantum state in a topological magnet
a, Crossing point energies EB and b, crossing point momenta (kx, ky) systematically extracted from cone dispersions observed in the ARPES spectra (magenta squares), same dataset as Fig. 2c (hν = 544 eV), with fit of the Weyl loop momentum trajectory and energy dispersion (cyan, see main text). The crossing point energies are parametrized by a polar angle θ defined by tan θ ≡ ky/kx. c, Weyl loop trajectory from DFT, with dotted lines indicating the DFT energy-momentum slices shown in Fig. 2b. The binding energy axes in (b) and (c) are collapsed58.
