Quantum Lifshitz point in the infinite dimensional Hubbard model
F. Günther, G. Seibold, J. Lorenzana
We show that the Gutzwiller variational wave function is surprisingly accurate for the computation of magnetic phase boundaries in the infinite dimensional Hubbard model. This allo…

Effective electron-electron and electron-phonon interactions in the Hubbard-Holstein model
G. Aprea, C. Di Castro, M. Grilli +1
We investigate the interplay between the electron-electron and the electron-phonon interaction in the Hubbard-Holstein model. We implement the flow-equation method to investigate w…
