Multi-Dirac and Weyl physics in heavy-fermion systems
JF Silva, E Miranda - Physical Review B, 2024 - APS
We have studied multi-Dirac/Weyl systems with arbitrary topological charge n in the
presence of a lattice of local magnetic moments. To do so we propose a multi-Dirac/Weyl …

Kondo breakdown in multi-orbital Anderson lattices induced by destructive hybridization interference
F Eickhoff, FB Anders - arXiv preprint arXiv:2401.04540, 2024 - arxiv.org
In this paper we consider a multi band extension to the periodic Anderson model. We use a
single site DMFT (NRG) in order to study the impact of the conduction band mediated …

Quantum impurity with local moment in one-dimensional quantum wires: A numerical renormalization group study
We study a Kondo state that is strongly influenced by its proximity to an ω− 1/2 singularity in
the metallic host density of states. This singularity occurs at the bottom of the band of a one …
