Ghost-RISB for Correlated Electron-Phonon Systems: Application to the Hubbard-Holstein Model
Samuele Giuli, Ricardo J. Campos-Lopes, Emin Moghadas +1
We develop a generalization of the ghost-rotationally-invariant slave-boson (ghost-RISB) method that incorporates local phonon modes coupled to arbitrary on-site electronic degrees…
Role of particle density in the Hall response of synthetic fermionic ladders: Lifshitz and Meissner-vortex transitions
Matteo Ferraretto, Matteo Acciai, Massimo Capone
The paper studies the Hall imbalance of non‑interacting fermionic ladders with synthetic magnetic flux, showing that the response depends strongly on particle density and is linked…
Quantum magic of strongly correlated fermions the Hubbard dimer
Edoardo Zavatti, Gabriele Bellomia, Massimo Capone
We study the non-stabilizerness (quantum magic) content of the Hubbard dimer, an analytically solvable, yet completely non-trivial, model of strongly correlated fermions. We consid…
First-principles real-space embedding theory of the superconducting proximity effect
Nicolas Baù, Nicolas Baù, Mitra Dowlatabadi +3
When a superconductor is placed in contact with a normal material, Cooper pairs penetrate the latter and induce superconductivity via the proximity effect. Despite its central role…
Local classical correlations between physical electrons in Hubbard systems
Gabriele Bellomia, Adriano Amaricci, Massimo Capone
We demonstrate that the local nonfreeness, an unbiased measure of correlation between electrons at a single lattice site, can be computed as the mutual information between local na…
Tracking the local order parameter through the Hubbard exciton decoherence time in the Mott-Hubbard insulator LaVO3
Alessandra Milloch, Paolo Franceschini, Pablo Villar-Arribi +9
The prototypical Mott-Hubbard insulator LaVO3 undergoes a structural phase transition accompanied by the onset of spin and orbital ordering below 140 K. By combining ultrafast opti…
