Particle-hole Symmetric Slave Boson Method for the Mixed Valence Problem

Liam L. H. Lau, Piers Coleman

We introduce an analytic slave boson method for treating the finite $U$ Anderson impurity model. Our approach introduces two bosons to track both $Q ⇌ Q \pm 1$ valenc…

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…
