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…
Multichannel Dyson equation: derivation and analysis
Gabriele Riva, Pina Romaniello, J. Arjan Berger
In a recent letter [Phys. Rev. Lett. 131, 216401] we presented the multichannel Dyson equation (MCDE) in which two or more many-body Green's functions are coupled. In this work we…
The multi-channel Dyson equation: coupling many-body Green's functions
Gabriele Riva, Pina Romaniello, J. Arjan Berger
We present the multi-channel Dyson equation that combines two or more many-body Green's functions to describe the electronic structure of materials. In this work we use it to model…
