Gutzwiller approach to the Bose-Hubbard model with random local impurities
P. Buonsante, F. Massel, V. Penna +1
Recently it has been suggested that fermions whose hopping amplitude is quenched to extremely low values provide a convenient source of local disorder for lattice bosonic systems r…

The fidelity approach to the Hubbard model
L. Campos Venuti, M. Cozzini, P. Buonsante +3
We use the fidelity approach to quantum critical points to study the zero temperature phase diagram of the one-dimensional Hubbard model. Using a variety of analytical and numerica…
