Photoemission spectral functions from the three-body Green's function
Gabriele Riva, Timothée Audinet, Matthieu Vladaj +2
We present an original strategy for the calculation of direct and inverse photo-emission spectra from first principles. The main goal is to go beyond the standard Green's function…
A Wigner molecule at extremely low densities: a numerically exact study
Miguel Escobar Azor, Léa Brooke, Stefano Evangelisti +4
In this work we investigate Wigner localization at very low densities by means of the exact diagonalization of the Hamiltonian. This yields numerically exact results. In particular…
Optical properties of periodic systems within the current-current response framework: pitfalls and remedies
D. Sangalli, A. Berger, C. Attaccalite +2
We compare the optical absorption of extended systems using the density-density and current-current linear response functions calculated within many-body perturbation theory. The t…
Photoemission Spectra from Reduced Density Matrices: the Band Gap in Strongly Correlated Systems
Stefano Di Sabatino, J. A. Berger, Lucia Reining +1
We present a method for the calculation of photoemission spectra in terms of reduced density matrices. We start from the spectral representation of the one-body Green's function G,…
