- Descripción
- We consider a generalised Hubbard Hamiltonian which is invariant under a Real Space Renormalisation Group. Within the present approximation, the Bravais lattice is replaced by a diamond-like hierarchical lattice. We calculate the phase diagram associated with the half-filled band Hubbard Hamiltonian in d = 1, 2 and 3, in the full range of the dimensionless Intra-atomic interaction U and hopping t parameters. The influence of the hierarchical lattice fractality is analised as well.
