Non-equilibrium critical properties of the Ising model on product graphs
R. Burioni, F. Corberi, A. Vezzani
We study numerically the non-equilibrium critical properties of the Ising model defined on direct products of graphs, obtained from factor graphs without phase transition (Tc = 0).…
Complex phase-ordering of the one-dimensional Heisenberg model with conserved order parameter
R. Burioni, F. Corberi, A. Vezzani
We study the phase-ordering kinetics of the one-dimensional Heisenberg model with conserved order parameter, by means of scaling arguments and numerical simulations. We find a rich…
Glassy features of a Bose Glass
P. Buonsante, F. Massel, V. Penna +1
We study a two-dimensional Bose-Hubbard model at a zero temperature with random local potentials in the presence of either uniform or binary disorder. Many low-energy metastable co…
Fractal geometry of Ising magnetic patterns: signatures of criticality and diffusive dynamics
E. Agliari, R. Burioni, D. Cassi +1
We investigate the geometric properties displayed by the magnetic patterns developing on a two-dimensional Ising system, when a diffusive thermal dynamics is adopted. Such a dynami…
Random walks interacting with evolving energy landscapes
E. Agliari, R. Burioni, D. Cassi +1
We introduce a diffusion model for energetically inhomogeneous systems. A random walker moves on a spin-S Ising configuration, which generates the energy landscape on the lattice t…
Diffusive thermal dynamics for the spin-S Ising ferromagnet
E. Agliari, R. Burioni, D. Cassi +1
We introduce an alternative thermal diffusive dynamics for the spin-S Ising ferromagnet realized by means of a random walker. The latter hops across the sites of the lattice and fl…
