Langevin simulations of a model for ultrathin magnetic films
Lucas Nicolao, Daniel A. Stariolo
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 fro…
Distributions of switching times of single-domain particles using a time quantified Monte Carlo method
Orlando V. Billoni, Daniel A. Stariolo
Using a time quantified Monte Carlo scheme we performed simulations of the switching time distribution of single mono-domain particles in the Stoner-Wohlfarth approximation. We con…
Competing Interactions, the Renormalization Group and the Isotropic-Nematic Phase Transition
Daniel G. Barci, Daniel A. Stariolo
We discuss 2D systems with Ising symmetry and competing interactions at different scales. In the framework of the Renormalization Group, we study the effect of relevant quartic int…
Langevin dynamics of fluctuation induced first order phase transitions: self consistent Hartree Approximation
Roberto Mulet, Daniel Stariolo
The Langevin dynamics of a system exhibiting a Fluctuation Induced First Order Phase Transition is solved within the self consistent Hartree Approximation. Competition between inte…
