Resonant optical cavities are essential components in mid-infrared applications. However, typical film-type cavities require multilayer stacks with a micron-thick spacer due to mid-infrared wavelengths, and their performance is limited by narrow freq

Topological singularity-induced Mott-like self-energy and its impact on Kondo cloud formation

Autor: Kang, Byungkyun, Brown, Zachary, Kim, Myoung-Hwan, Kim, Hyunsoo, Park, Chul Hong

We discovered that abnormal Mott physics can emerge even in weakly correlated 4f fermions through their interplay with topological singularity. Employing ab initio many-body perturbation theory combined with dynamical mean field theory, we show that

Dual Nature of Magnetism Driven by Momentum Dependent f-d Kondo Hybridization

Autor: Kang, Byungkyun, Lee, Yongbin, Ke, Liqin, Kim, Hyunsoo, Kim, Myoung-Hwan

Intricate nature of magnetism in uranium-based Kondo lattices is a consequence of correlations between U-5$f$ and conduction electrons. Using linearized quasiparticle self-consistent GW plus dynamical mean-field theory, we demonstrate a crossover fro
