On the Fermi Liquid to Polaron Crossover I: General Results
arXiv:cond-mat/9602154 · doi:10.1103/PhysRevB.54.5389
Abstract
We use analytic techniques and the dynamical mean field method to study the crossover from fermi liquid to polaron behavior in models of electrons interacting with dispersionless classical phonons.
