Unraveling Fermi liquid charge and heat transport in RuO
Harrison LaBollita, Fabian B. Kugler, Antoine Georges +1
RuO is a multi-orbital Fermi liquid for which an array of complementary experimental measurements has recently become available, making it a stringent testbed for quantitative…
Quasiparticle to local moment crossover in bad metals
A. Chen, F. B. Kugler, P. Doležal +4
Non-Fermi-liquid charge transport in the vicinity of electronic instabilities has been intensely studied for decades. Deviations from in bad and strange metal…
Electron-phonon origins of unconventional resistivity in moderately correlated perovskite oxides
Jennifer Coulter, Fabian B. Kugler, Harrison LaBollita +2
Transition-metal perovskite oxides exhibit moderately correlated metallic phases, several of which exhibit a resistivity scaling up to temperatures far exceeding the regime w…
Low-temperature transport in high-conductivity correlated metals: a density-functional plus dynamical mean-field study of cubic perovskites
Harrison LaBollita, Jeremy Lee-Hand, Fabian B. Kugler +6
While methods based on density-functional perturbation theory have dramatically improved our understanding of electron-phonon contributions to transport in materials, methods for a…
Non-Fermi liquid quasiparticles in strain-tuned Sr2RuO4
A. Hunter, C. Putzke, F. B. Kugler +23
Interacting electrons can form metallic states beyond the Fermi liquid paradigm, a conceptual frontier of many-body physics mainly explored via bulk thermodynamics and transport. I…
Hund flat band in a frustrated spinel oxide
Dongjin Oh, Alexander Hampel, Joshua P. Wakefield +26
Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenom…
Fermi-Liquid Resistivity: Dynamical Mean-Field Theory Meets Experiment
Fabian B. Kugler, Jeremy Lee-Hand, Harrison LaBollita +6
Direct-current resistivity is a key probe for the physical properties of materials. In metals, Fermi-liquid (FL) theory serves as the basis for understanding transport. A beh…
Nature of metallic and insulating domains in the CDW system 1T-TaSe2
M. Straub, F. Petocchi, C. Witteveen +12
We study the electronic structure of bulk 1T-TaSe in the charge density wave phase at low temperature. Our spatially and angle resolved photoemission (ARPES) data show insulati…
LiV2O4: Hund-Assisted Orbital-Selective Mottness
Martin Grundner, Fabian B. Kugler, Olivier Parcollet +3
We show that the remarkably small Fermi-liquid coherence scale and large effective mass observed in LiVO are due to the proximity of a Hund-assisted orbital-selective Mott…
Low-energy perspective on two-orbital Hund metals and the case of LaNiO2
Fabian B. Kugler, Chang-Jong Kang, Gabriel Kotliar
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-laye…
Vacancy-induced tunable Kondo effect in twisted bilayer graphene
Yueqing Chang, Jinjing Yi, Ang-Kun Wu +5
In single sheets of graphene, vacancy-induced states have been shown to host an effective spin-1/2 hole that can be Kondo-screened at low temperatures. Here, we show how these vaca…
