We formulate a bulk spectroscopic method for direct measurement of thetopological invariant of nondegenerate band crossings in Weyl semimetals. Wedemonstrate how polarization-resolved resonant x-ray scattering captures thewinding of the Berry flux around Weyl nodes. The spectra obtained by theproposed strategy feature an integer number of zero-crossings that is directlyrelated to the topological charge of the measured nodes. We benchmark theproposed protocol on TaAs, using realistic low-energy models derived fromdensity-functional theory to accurately represent the states close to the Fermilevel, including sizable deviations from the idealized linear dispersion. Weconclude that the proposed measurement, which is within the reach of currentexperimental setups, yields direct signatures of nontrivial band topology inspectroscopy of three-dimensional bulk matter.
