Spectral signatures of spin textures and the emergence of a pseudogap
Matteo Quinzi, Andrea Pintus, Tommaso Chiarotti +2
Periodic solids with strongly interacting electrons display phenomena -- from Mott localization to high-temperature superconductivity -- that escape conventional band theory. Effor…
Dynamical vertex approximation for retarded interactions: Application to the Hubbard-Holstein model
Emin Moghadas, Samuele Giuli, Massimo Capone +1
We extend the dynamical vertex approximation (DA), in its most commonly used ladder-version, to systems with retarded electronic interactions. Such an extended scheme, which we…
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…
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…
More is uncorrelated: Tuning the local correlations of SU() Fermi-Hubbard systems via controlled symmetry breaking
Edoardo Zavatti, Gabriele Bellomia, Matteo Ferraretto +2
Cold-atom experiments based on alkali-like atoms provide us with a tool to experimentally realize Hubbard models with a large number of components. The value of can be seen…
Bath parameterization in multi-band cluster Dynamical Mean-Field Theory
Diego Florez-Ablan, Carlos Mejuto-Zaera, Massimo Capone
Accurate and reliable algorithms to solve complex impurity problems are instrumental to a routine use of quantum embedding methods for material discovery. In this context, we emplo…
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…
Next-generation EDIpack: A Lanczos-based package for quantum impurity models featuring general broken-symmetry phases, flexible bath topologies and multi-platform interoperability
Lorenzo Crippa, Igor Krivenko, Samuele Giuli +10
We present a next-generation version of EDIpack, a flexible, high-performance numerical library using Lanczos-based exact diagonalization to solve generic quantum impurity problems…
Altermagnetism from interaction-driven itinerant magnetism
Samuele Giuli, Carlos Mejuto-Zaera, Massimo Capone
Altermagnetism, a new phase of collinear spin-order sharing similarities with antiferromagnets and ferromagnets, has introduced a new guiding principle for spintronic/thermoelectri…
Competing Correlated Insulators in multi-orbital systems coupled to phonons
A. Scazzola, A. Amaricci, M. Capone
We study the interplay between electron-electron interaction and a Jahn-Teller phonon coupling in a two-orbital Hubbard model. We demonstrate that the e-ph interaction coexists wit…
Mott transitions with partially-filled correlated orbitals
Adriano Amaricci, Luca de' Medici, Massimo Capone
We investigate the metal-insulator Mott transition in a generalized version of the periodic Anderson model, in which a band of itinerant electrons is hybridrized with a narrow and…
Electronic transport and dynamics in correlated heterostructures
G. Mazza, A. Amaricci, M. Capone +1
We investigate by means of the time-dependent Gutzwiller approximation the transport properties of a strongly-correlated slab subject to Hubbard repulsion and connected with to two…
Inhomogeneous BCS-BEC crossover for trapped cold atoms in optical lattices
A. Amaricci, A. Privitera, M. Capone
The BCS-BEC crossover in a lattice is a powerful paradigm to understand how a superconductor deviates from the Bardeen-Cooper-Schrieffer physics as the attractive interaction incre…
Augmented hybrid exact-diagonalization solver for dynamical mean field theory
C. Weber, A. Amaricci, M. Capone +1
We present a new methodology to solve the Anderson impurity model, in the context of dynamical mean-field theory, based on the exact diagonalization method. We propose a strategy t…
Polarons and Bipolarons in Holstein and Holstein models by Dynamical Mean Field Theory
S. Ciuchi, M. Capone, E. Cappelluti +1
The results of a comparative study of electronic spectral properties as well as phonon Probability Distribution Function (PDF) are reported. The study is done using Dynamical Mean…
