Metric Features of a Dipolar Model
M. Casartelli, L. Dall'Asta, E. Rastelli +1
The lattice spin model, with nearest neighbor ferromagnetic exchange and long range dipolar interaction, is studied by the method of time series for observables based on cluster co…
Bose-Einstein condensation in inhomogeneous Josephson arrays
R. Burioni, D. Cassi, I. Meccoli +3
We show that spatial Bose-Einstein condensation of non-interacting bosons occurs in dimension d < 2 over discrete structures with inhomogeneous topology and with no need of externa…
Cutting-Decimation Renormalization for diffusive and vibrational dynamics on fractals
Raffaella Burioni, Davide Cassi, Sofia Regina
Recently, we pointed out that on a class on non exactly decimable fractals two different parameters are required to describe diffusive and vibrational dynamics. This phenomenon we…
Diffusion on non exactly decimable tree-like fractals
Raffaella Burioni, Davide Cassi, Alberto Pirati +1
We calculate the spectral dimension of a wide class of tree-like fractals by solving the random walk problem through a new analytical technique, based on invariance under generaliz…
