Inelastic x-ray (or n + or e – ) scattering (k 2 ,ω 2 ) (k 1 ,ω 1 ) Fluctuation-Dissipation theorem: Bell Jar I(k,ω) ~ – Im[χ(k,ω)] k = k 1 – k 2 Pendulum ω = ω 1 – ω 2
Inelastic x-ray (or n + or e – ) scattering Couple light to <strong>electron</strong>s (Lorentz force law) Be sure to second-quantize to get photons Multiply out to get interactions Do perturbation theory (1st Born approximation) Turns out to be a Green’s function
