A newish area of interactions between quantum Monte Carlo (QMC) and experiments is in spin spectra. Recent improvements in stochastic analytic continuation have made it much easier to compare/extract the dynamical spin structure factor, which corresponds to the results of inelastic neutron scattering experiments.
My problem is that I don't have a good intuition for interpreting these spectra. They represent a complex quantity that includes density of states, dispersion relations, gaps, and finite-temperature effects with a layer of noise on top.
How to identify important features from the experiments avoid getting confused by artifacts?
