Charge-fluctuation contribution to the Raman response in superconducting cuprates
S. Caprara, C. Di Castro, M. Grilli +1
We calculate the Raman response contribution due to collective modes, finding a strong dependence on the photon polarizations and on the characteristic wavevectors of the modes. We…

Phase Separation close to the density-driven Mott transition in the Hubbard-Holstein model
M. Capone, G. Sangiovanni, C. Castellani +2
The density driven Mott transition is studied by means of Dynamical Mean-Field Theory in the Hubbard-Holstein model, where the Hubbard term leading to the Mott transition is supple…
