Domain walls, canted states and stripe width variation in ultrathin magnetic films with perpendicular anisotropy
Santiago A. Pighin, Orlando V. Billoni, Daniel A. Stariolo +1
Stripe width variation in ultrathin magnetic films is a well known phenomenon still not well understood. We analyze this problem considering a 2D Heisenberg model with ferromagneti…
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…
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…
Similar self-organizing scale-invariant properties characterize early cancer invasion and long range species spread
D. E. Marco, S. A. Cannas, M. A. Montemurro +2
Occupancy of new habitats through dispersion is a central process in nature. In particular, long range dispersal is involved in the spread of species and epidemics, although it has…
