Dynamics of continuous-time quantum walks in restricted geometries
E. Agliari, A. Blumen, O. Muelken
We study quantum transport on finite discrete structures and we model the process by means of continuous-time quantum walks. A direct and effective comparison between quantum and c…
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…
Criticality in diluted ferromagnet
Elena Agliari, Adriano Barra, Federico Camboni
We perform a detailed study of the critical behavior of the mean field diluted Ising ferromagnet by analytical and numerical tools. We obtain self-averaging for the magnetization a…
Configurations and Observables in an Ising Model with Heat Flow
E. Agliari, M. Casartelli, A. Vezzani
We study a two dimensional Ising model between thermostats at different temperatures. By applying the recently introduced KQ dynamics, we show that the system reaches a steady stat…
