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…
