Tunable Skyrmions in a Topological Wigner Crystal
David A. Dahlbom, Daniel Kaplan, Premala Chandra +1
In low density systems with strong interactions electrons are expected to crystallize into a Wigner solid. Recently, advances in two-dimensional systems where electrons carry Berry…

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…
