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…

Functional theory of the occupied spectral density

Andrea Ferretti, Nicola Marzari

We address the problem of interacting electrons in an external potential by introducing the occupied spectral density as fundamental variable. First, we formulate…

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…
