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…
A Unified Geometric Framework for Understanding Collider Event Manifolds
Tianji Cai, Hancheng Li
By defining notions of similarity between collider events, metrics give rise to event manifolds with nontrivial geometric structure. Understanding these structures and their relati…
Dynamical pseudopotentials
Matteo Quinzi, Tommaso Chiarotti, Nicola Marzari
Pseudopotential theory has greatly driven first-principles calculations in materials, replacing the explicit treatment of the chemically inert core electrons with an effective pote…
First-principles real-space embedding theory of the superconducting proximity effect
Nicolas Baù, Mitra Dowlatabadi, Tommaso Chiarotti +2
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…
Electronic Structure and Dynamical Correlations in Antiferromagnetic BiFeO
Yihan Wu, Mario Caserta, Tommaso Chiarotti +1
We study the electronic structure and dynamical correlations in antiferromagnetic BiFeO, a prototypical room-temperature multiferroic, using a variety of static and dynamical f…
Self-consistent dynamical Hubbard functional for correlated solids
Tommaso Chiarotti, Matteo Quinzi, Andrea Pintus +3
Many-body functionals of the Green's function can provide fundamental advances in electronic-structure calculations, due to their ability to accurately predict both spectral and th…
Dynamical Hubbard approach to correlated materials: the case of transition-metal monoxides
Mario Caserta, Tommaso Chiarotti, Marco Vanzini +1
Electronic correlations beyond static mean-field theories are of fundamental importance in describing the properties of complex materials - such as transition-metal oxides - where…
Broken symmetry solutions in one-dimensional lattice models via many-body perturbation theory
Matteo Quinzi, Tommaso Chiarotti, Marco Gibertini +1
In this work we study self-consistent solutions in one-dimensional lattice models obtained via many-body perturbation theory. The Dyson equation is solved in a fully self-consisten…
On Green's function embedding using sum-over-pole representations
Andrea Ferretti, Tommaso Chiarotti, Nicola Marzari
In Green's function theory, the total energy of an interacting many-electron system can be expressed in a variational form using the Klein or Luttinger-Ward functionals. Green's fu…
Energies and spectra of solids from the algorithmic inversion of dynamical Hubbard functionals
Tommaso Chiarotti, Andrea Ferretti, Nicola Marzari
Energy functionals of the Green's function can simultaneously provide spectral and thermodynamic properties of interacting electrons' systems. Though powerful in principle, these f…
A unified Green's function approach for spectral and thermodynamic properties from algorithmic inversion of dynamical potentials
Tommaso Chiarotti, Nicola Marzari, Andrea Ferretti
Dynamical potentials appear in many advanced electronic-structure methods, including self-energies from many-body perturbation theory, dynamical mean-field theory, electronic-trans…
Frequency dependence in GW made simple using a multi-pole approximation
Dario A. Leon, Claudia Cardoso, Tommaso Chiarotti +3
In the approximation, the screened interaction is a non-local and dynamical potential that usually has a complex frequency dependence. A full description of such dependenc…
