Anomalous propagators and the particle-particle channel: Bethe-Salpeter equation
Antoine Marie, Pina Romaniello, Xavier Blase +1
The Bethe-Salpeter equation has been extensively employed to compute the two-body electron-hole propagator and its poles which correspond to the neutral excitation energies of the…
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…
Anomalous propagators and the particle-particle channel: Hedin's equations
Antoine Marie, Pina Romaniello, Pierre-François Loos
Hedin's equations provide an elegant route to compute the exact one-body Green's function (or propagator) via the self-consistent iteration of a set of non-linear equations. Its fi…
