Performance of wave function and Green's functions based methods for non equilibrium many-body dynamics
Cian C. Reeves, Gaurav Harsha, Avijit Shee +5
Theoretical descriptions of non equilibrium dynamics of quantum many-body systems essentially employ either (i) explicit treatments, relying on truncation of the expansion of the m…
Towards the solution of the many-electron problem in real materials: equation of state of the hydrogen chain with state-of-the-art many-body methods
Mario Motta, David M. Ceperley, Garnet Kin-Lic Chan +18
We present numerical results for the equation of state of an infinite chain of hydrogen atoms. A variety of modern many-body methods are employed, with exhaustive cross-checks and…
Ionization potentials and electron affinities from the extended Koopmans' theorem in self-consistent Green's function theory
Alicia Rae Welden, Jordan J. Phillips, Dominika Zgid
One-body Green's function theories implemented on the real frequency axis offer a natural formalism for the unbiased theoretical determination of quasiparticle spectra in molecules…
Fractional charge and spin errors in self-consistent Green's function theory
Jordan J. Phillips, Alexei A. Kananenka, Dominika Zgid
We examine fractional charge and spin errors in self-consistent Green's function theory within a second-order approximation (GF2). For GF2 it is known that the summation of diagram…
