Fermi surface dichotomy on systems with fluctuating order
M. Grilli, G. Seibold, A. Di Ciolo +1
We investigate the effect of a dynamical collective mode coupled with quasiparticles at specific wavevectors only. This coupling describes the incipient tendency to order and produ…
Charge instabilities and electron-phonon interaction in the Hubbard-Holstein model
A. Di Ciolo, J. Lorenzana, M. Grilli +1
We consider the Hubbard-Holstein model in the adiabatic limit to investigate the effects of electron-electron interactions on the electron-phonon coupling. To this aim we compute a…
Time-dependent Gutzwiller theory of pairing fluctuations in the Hubbard model
G. Seibold, F. Becca, J. Lorenzana
We present a method to compute pairing fluctuations on top of the Gutzwiller approximation (GA). Our investigations are based on a charge-rotational invariant GA energy functional…
Slave-boson based configuration-interaction approach for the Hubbard model
G. Seibold
Based on the Kotliar-Ruckenstein slave-boson scheme we develop a configuration-interaction (CI) approach which is suitable to improve the energy of symmetry-broken saddle-point sol…
