Electronic correlations and dynamical screening with ab initio quantum embedding
Chia-Nan Yeh, Francesco Petocchi, Alexander Hampel +4
First-principles descriptions of correlated quantum materials require a simultaneous treatment of strong local many-body effects and nonlocal dynamical screening. We present an eff…
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…
Enhanced Strange Metallicity due to Hubbard-U Coulomb Repulsion
Andrew Hardy, Olivier Parcollet, Antoine Georges +1
We solve a model of electrons with Hubbard- Coulomb repulsion and a random Yukawa coupling to a two-dimensional bosonic bath, using an extended dynamical mean field theory schem…
The Hund-metal path to strong electronic correlations
Antoine Georges, Gabriel Kotliar
Atomic physics has a profound impact on the physical properties of correlated electron materials. This article describes a prime example of this phenomenon. We provide a non-techni…
