Non-equilibrium structures and slow dynamics in a two dimensional spin system with competitive long range and short range interactions
Omar Osenda, Francisco A. Tamarit, Sergio A. Cannas
We introduce a lattice spin model that mimics a system of interacting particle through a short range repulsive potential and a long range attractive power law decaying potential. W…
Non-equilibrium Characterization of Spinodal Points using Short Time Dynamics
Ernesto S. Loscar, Ezequiel E. Ferrero, Tomas S. Grigera +1
Though intuitively appealing, the concept of spinodal is rigourously defined only in systems with infinite range interactions (mean field systems). In short-range systems, a pseudo…
Emergent self-organized complex network topology out of stability constraints
J. I. Perotti, O. V. Billoni, F. A. Tamarit +2
Although most networks in nature exhibit complex topology the origins of such complexity remains unclear. We introduce a model of a growing network of interacting agents in which e…
Exponential equilibration by slow cooling in the planar random-anisotropy magnet: experiments and simulations
Donald R. Taylor, Orlando V. Billoni, Sergio A. Cannas +1
Neutron measurements of the equilibration of the staggered magnetization in DyAs(0.35)V(0.65)O4 are compared with Monte Carlo simulations of spin dynamics in a planar random-anisot…
Interplay between coarsening and nucleation in an Ising model with dipolar interactions
S. A. Cannas, M. F. Michelon, D. A. Stariolo +1
We study the dynamical behavior of a square lattice Ising model with exchange and dipolar interactions by means of Monte Carlo simulations. After a sudden quench to low temperature…
