We propose a model for the formation of patterns in the visual cortex. The dynamical units of the model are Kuramoto phase oscillators that interact through a complex network structure embedded inâ€¦ (More)

Although most networks in nature exhibit complex topologies, the origins of such complexity remain unclear. We propose a general evolutionary mechanism based on global stability. This mechanism isâ€¦ (More)

The two-dimensional Ising model with competing short range ferromagnetic interactions and long range antiferro-magnetic interactions is perhaps the most simple one containing the minimal microscopicâ€¦ (More)

We introduce a model for granular flow in a one-dimensional rice pile that incorporates rolling effects through a long-range rolling probability for the individual rice grains proportional toâ€¦ (More)

In this work we study the effects of introducing long range interactions in the Bak-Sneppen (BS) model of biological evolution. We analyze a recently proposed version of the BS model where theâ€¦ (More)

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 temperatures, we find that theâ€¦ (More)

We analyze the nature of the phase transition from a smectic stripe phase to a tetragonal phase predicted in analytic studies by Abanov et al. @Phys. Rev. B 51, 1023 ~1995!# and observed inâ€¦ (More)

We propose a mechanism to explain the phenomenon of positive exchange bias on magnetic bilayered systems. The mechanism is based on the formation of a domain wall at a disordered interface duringâ€¦ (More)

We solve the Langevin dynamics of d-dimensional ferromagnetic spherical models with interactions that decay with distance as râˆ’(d+Ïƒ). The long time dynamics of correlations and responses are studiedâ€¦ (More)
