How to derive the Clausius–Mossotti relation using Feynman diagrams?
The Clausius–Mossotti relation is usually derived by assuming that a molecular in a crystal is surrounded by a spherical hole, or by the $- \frac{1}{3k^2} \delta(\boldsymbol{R})$ term in the dyadic Gr …

How to derive the Clausius–Mossotti relation using Feynman diagrams?
After several months I finally find out how. The C-M relation can't be obtained by integrating out electron propagators; what we need is actually integrating out microscopic electromagnetic fields.
Th …
