Band structures in coupled-cluster singles-and-doubles Green's function (GFCCSD)

Yoritaka Furukawa, Taichi Kosugi, Hirofumi Nishi +1

We demonstrate that coupled-cluster singles-and-doubles Green's function (GFCCSD) method is a powerful and prominent tool drawing the electronic band structures and the total energ…

Comparison of Green's functions for transition metal atoms using self-energy functional theory and coupled-cluster singles and doubles (CCSD)

Taichi Kosugi, Hirofumi Nishi, Yoritaka Furukawa +1

We demonstrate in the present study that self-consistent calculations based on the self-energy functional theory (SFT) are possible for the electronic structure of realistic system…

Quasiparticle energy spectra of isolated atoms from coupled-cluster singles and doubles (CCSD): Comparison with exact CI calculations

Hirofumi Nishi, Taichi Kosugi, Yoritaka Furukawa +1

In this study, we have calculated single-electron energy spectra via the Green's function based on the coupled-cluster singles and doubles (GFCCSD) method for isolated atoms from H…
