Barrier crossing in a two-state system: Effect of bias and stochastic fields
Sara Oliver-Bonafoux, Raúl Toral, Amitabha Chakrabarti
We study barrier crossing in a two-state system, namely the kinetic Ising model, in the presence of a weak bias field and spatially homogeneous, but time-dependent, Gaussian random…

Stochastic field effects in a two-state system: symmetry breaking and symmetry restoring
Sara Oliver-Bonafoux, Raul Toral, Amitabha Chakrabarti
We study the Ising model under a time-varying, but spatially homogeneous, Gaussian random magnetic field. In the Monte Carlo simulations, we go beyond the standard analysis of the…
