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…
Quantum Monte Carlo assessment of embedding for for strongly correlated defects: interplay between mean-field starting point and interactions
Kevin G. Kleiner, Sonali Joshi, Rohan Joshi +5
Point defects are of interest for many applications, from quantum sensing to modifying bulk properties of materials. Because of their localized orbitals, the electronic states are…
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…
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…
Stabilizing the calculation of the self-energy in dynamical mean-field theory using constrained residual minimization
Harrison LaBollita, Jason Kaye, Alexander Hampel
We propose a simple and efficient method to calculate the electronic self-energy in dynamical mean-field theory (DMFT), addressing a numerical instability often encountered when so…
