Critical properties of the band-insulator-to-Mott-insulator transition in the strong-coupling limit of the ionic Hubbard model
L. Tincani, R. M. Noack, D. Baeriswyl
We investigate the neutral-to-ionic insulator-insulator transition in one-dimensional materials by treating a strong-coupling effective model based on the ionic Hubbard model using…
Wilson's renormalization group applied to 2D lattice electrons in the presence of van Hove singularities
B. Binz, D. Baeriswyl, B. Doucot
The weak coupling instabilities of a two dimensional Fermi system are investigated for the case of a square lattice using a Wilson renormalization group scheme to one loop order. W…
Solution of the infinite range t-J model
B. Binz, X. Zotos, D. Baeriswyl
The t-J model with constant t and J between any pair of sites is studied by exploiting the symmetry of the Hamiltonian with respect to site permutations. For a given number of elec…
Jellium model of metallic nanocohesion
C. A. Stafford, D. Baeriswyl, J. Burki
A unified treatment of the cohesive and conducting properties of metallic nanostructures in terms of the electronic scattering matrix is developed. A simple picture of metallic nan…
Cooper pair delocalization in disordered media
M. A. N. Araujo, M. Dzierzawa, C. Aebischer +1
We discuss the effect of disorder on the coherent propagation of the bound state of two attracting particles. It is shown that a result analogous to the Anderson theorem for dirty…
Low density ferromagnetism in the Hubbard model
P. Pieri, S. Daul, D. Baeriswyl +2
A single-band Hubbard model with nearest and next-nearest neighbour hopping is studied for , 2, 3, using both analytical and numerical techniques. In one dimension, saturated…
