Reply to: "Extracting Kondo temperature of strongly-correlated systems from the inverse local magnetic susceptibility"
Xiaoyu Deng, Katharina M. Stadler, Kristjan Haule +4
This is a reply to A. A. Katanin's comment [A. A. Katanin, Nat. Commun. 12, 1433 (2021); arXiv:2103.02966] on our paper [X. Deng et al., Nat. Commun. 10, 2721 (2019); arXiv:1708.05…
Differentiating Hund from Mott physics in a three-band Hubbard-Hund model: Temperature dependence of spectral, transport, and thermodynamic properties
K. M. Stadler, G. Kotliar, S. -S. B. Lee +2
We study the interplay between Mott physics, driven by Coulomb repulsion U, and Hund physics, driven by Hund's coupling J, for a minimal model for Hund metals, the orbital-symmetri…
Global phase diagram of a spin-orbital Kondo impurity model and the suppression of Fermi-liquid scale
Y. Wang, E. Walter, S. -S. B. Lee +4
Many correlated metallic materials are described by Landau Fermi-liquid theory at low energies, but for Hund metals the Fermi-liquid coherence scale is found to be…
Uncovering Non-Fermi-Liquid Behavior in Hund Metals: Conformal Field Theory Analysis of an SU(2)SU(3) Spin-Orbital Kondo Model
E. Walter, K. M. Stadler, S. -S. B. Lee +4
Hund metals have attracted attention in recent years due to their unconventional superconductivity, which supposedly originates from non-Fermi-liquid (NFL) properties of the normal…
Hundness versus Mottness in a three-band Hubbard-Hund model: On the origin of strong correlations in Hund metals
Katharina M. Stadler, Gabriel Kotliar, Andreas Weichselbaum +1
Hund metals are multi-orbital systems with moderate Coulomb interaction, , and sizeable Hund's rule coupling, , that aligns the spins in different orbitals. They show stron…
Signatures of Mottness and Hundness in archetypal correlated metals
Xiaoyu Deng, Katharina M. Stadler, Kristjan Haule +3
Physical properties of multi-orbital materials depend not only on the strength of the effective interactions among the valence electrons but also on their type. Strong correlations…
Open Wilson chains for quantum impurity models: Keeping track of all bath modes
Benedikt Bruognolo, Nils-Oliver Linden, Frauke Schwarz +6
When constructing a Wilson chain to represent a quantum impurity model, the effects of truncated bath modes are neglected. We show that their influence can be kept track of systema…
Interleaved numerical renormalization group as an efficient multiband impurity solver
K. M. Stadler, A. K. Mitchell, J. von Delft +1
Quantum impurity problems can be solved using the numerical renormalization group (NRG), which involves discretizing the free conduction electron system and mapping to a `Wilson ch…
