Ground and excited-state properties of the extended Hubbard dimer from the multichannel Dyson equation

Stefano Paggi, J. Arjan Berger, Pina Romaniello

We have recently presented the multichannel Dyson equation as an alternative to the standard single-channel Dyson equation. While the latter involves a single many-body Green's fun…

Multichannel Dyson equations for even- and odd-order Green's functions: application to double excitations

Gabriele Riva, Théodore Fischer, Stefano Paggi +2

We extend the concept of the multichannel Dyson equation that we have recently derived to model photoemission spectra by coupling the one- and the three-body Green's functions, to…
