Dynamical behavior across the Mott transition of two bands with different bandwidths
Michel Ferrero, Federico Becca, Michele Fabrizio +1
We investigate the role of the bandwidth difference in the Mott metal-insulator transition of a two-band Hubbard model in the limit of infinite dimensions, by means of a Gutzwiller…

Quantum phase transition in easy-axis antiferromagnetic integer-spin chains
M. Capone, S. Caprara, L. Cataldi
Antiferromagnetic Heisenberg integer-spin chains are characterized by a spin-liquid ground state with no long-range order, due to the relevance of quantum fluctuations. Spin anisot…

The Small Polaron Crossover: Role of Dimensionality
M. Capone, S. Ciuchi, C. Grimaldi
The crossover from quasi free electron to small polaron in the Holstein model for a single electron is studied by means of both exact and self-consistent calculations in one dimens…
