Oscillate and Renormalize: Fast Phonons Reshape the Kondo Effect in Flat Band Systems
Liam L. H. Lau, Andreas Gleis, Daniel Kaplan +2
We examine the interplay between electron correlations and phonons in an Anderson-Holstein impurity model with an Einstein phonon. When the phonons are slow compared to charge fluc…
