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…
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…
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…
Frequency-Dependent Superconducting States From the Two-Time Linear Response Theory: Application To SrRuO
Olivier Gingras, Antoine Georges, Olivier Parcollet
We investigate the possible superconducting instabilities of strongly correlated electron materials using a generalization of linear response theory to external pairing fields depe…
Exact numerical solution of the fully-connected classical and quantum Heisenberg spin glass
Nikita Kavokine, Markus Müller, Antoine Georges +1
We present the mean field solution of the quantum and classical Heisenberg spin glasses, using the combination of a high precision numerical solution of the Parisi full replica sym…
Mott transition at large orbital degeneracy: dynamical mean-field theory
S. Florens, A. Georges, G. Kotliar +1
We study analytically the Mott transition of the N-orbital Hubbard model using dynamical mean-field theory and a low-energy projection onto an effective Kondo model. It is demonstr…
Quantum Fluctuations of a Nearly Critical Heisenberg Spin Glass
A. Georges, O. Parcollet, S. Sachdev
We describe the interplay of quantum and thermal fluctuations in the infinite-range Heisenberg spin glass. This model is generalized to SU(N) symmetry, and we describe the phase di…
