Many-Body Effective Energy Theory: photoemission at strong correlation
S. Di Sabatino, J. A. Berger, P. Romaniello
In this work we explore the performance of a recently derived many-body effective energy theory for the calculation of photoemission spectra in the regime of strong electron correl…
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,…
Reduced Density-Matrix Functional Theory: correlation and spectroscopy
Stefano Di Sabatino, Jan A. Berger, Lucia Reining +1
In this work we explore the performance of approximations to electron correlation in reduced density-matrix functional theory (RDMFT) and of approximations to the observables calcu…
