Extended Data Fig. 8: Calculated stereogram of the electronic susceptibility for the Fermi surface map of CoSi.
From: Tunable topologically driven Fermi arc van Hove singularities
Stereogram of the electronic susceptibility around the \(\bar{{{\Gamma }}}\)-point. Up to symmetry-equivalent scattering vectors, the strong peaks represent different peaks in the q-plots in the scattering BZ, labeled Q. The Q-vectors, nearest and next-nearest to the \(\bar{{{\Gamma }}}\)-point are labeled Q1 and Q2, respectively. The Q1-vector is annotated by the green arrow, potentially connected to the nesting vectors inside the intra-helicoid arc van Hove singularity. The Q2-vector is annotated by the cyan arrow, potentially connected to nesting vectors linking the nearest inter-helicoid arc van Hove singularity. The white box highlights regions of negligible weak intensities.
