Langevin simulations of model for ultrathin magnetic films
Nicolao, Lucas; Stariolo, Daniel Adrian (2007) [Artigo de periódico]We show results from simulations of the Langevin dynamics of a two-dimensional scalar model with competing interactions for ultrathin magnetic films. We find a phase transition from a high temperature disordered phase to ... -
Langevin simulations of stripe forming systems with long-range isotropic competing interactions
Nicolao, Lucas; Mendoza Coto, Alejandro; Stariolo, Daniel Adrian (2016) [Artigo de periódico]We address the critical properties of the isotropic-nematic phase transition in stripe forming systems. We focus on isotropic models in which a short range attractive interaction competes with a long range repulsive ... -
Nature of long-range order in stripe-forming systems with long-range repulsive interactions
Mendoza Coto, Alejandro; Stariolo, Daniel Adrian; Nicolao, Lucas (2015) [Artigo de periódico]We study two dimensional stripe forming systems with competing repulsive interactions decaying as r−α.We derive an effective Hamiltonian with a short-range part and a generalized dipolar interaction which depends on the ... -
Spatial correlation functions and dynamical exponents in very large samples of four-dimensional spin glasses
Nicolao, Lucas; Parisi, Giorgio; Ricci-Tersenghi, Federico (2014) [Artigo de periódico]The study of the low temperature phase of spin glass models by means of Monte Carlo simulations is a challenging task, because of the very slow dynamics and the severe finite-size effects they show. By exploiting at the ...
