Heavy fermions in frustrated Hund's metal with portions of incipient flat bands

Y Wang - Physical Review B, 2025 - APS
Flat bands induced by destructive interference of hop**s in frustrated lattices such as
kagome metals, have been extensively studied in recent years. However, such flat bands …

Computing local multipoint correlators using the numerical renormalization group

SSB Lee, FB Kugler, J von Delft - Physical Review X, 2021 - APS
Local three-and four-point correlators yield important insight into strongly correlated systems

X-symbols for non-Abelian symmetries in tensor networks

A Weichselbaum - Physical Review Research, 2020 - APS
The full exploitation of non-Abelian symmetries in tensor network states (TNSs) derived from
a given lattice Hamiltonian is attractive in various aspects. From a theoretical perspective, it …

Emergent properties of the periodic Anderson model: A High-resolution, real-frequency study of heavy-fermion quantum criticality

cellular dynamical mean-field theory (CDMFT), with the numerical renormalization group …

Low-energy perspective on two-orbital Hund metals and the case of

FB Kugler, CJ Kang, G Kotliar - Physical Review B, 2024 - APS
The Hund-metal route to strong correlations continues to attract large interest in the
condensed-matter community. The question arose to what extent it applies to the infinite …

Fe‐Vacancies Manipulate Kondo Screening States in the d‐Orbital Kondo Lattice of Fe3‐xGeTe2 (x = 0.07–0.54)

H Xu, M Zhao, S Xu, Y **, J Zhang, H Feng… - Small …, 2024 - Wiley Online Library
Manipulating the electronic correlation is a long‐term issue in the Kondo regime. Based on
the pioneer successes in many localized f‐orbital systems, further achievements in more …

Emergent moments in a Hund's impurity

V Drouin-Touchette, EJ König, Y Komijani, P Coleman - Physical Review B, 2021 - APS
Motivated by the relevance of Hund's coupling in the context of multiorbital superconductors,
we revisit the problem of a multiorbital Kondo impurity with Hund's interaction. Using …

Differentiating Hund from Mott physics in a three-band Hubbard-Hund model: Temperature dependence of spectral, transport, and thermodynamic properties

KM Stadler, G Kotliar, SSB Lee, A Weichselbaum… - Physical Review B, 2021 - APS
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 …
