Numerical methods for quasi-stationary distributions
Sara Oliver-Bonafoux, Javier Aguilar, Tobias Galla +1
In stochastic processes with absorbing states, the quasi-stationary distribution provides valuable insights into the long-term behaviour prior to absorption. In this work, we revis…

Complete aging in the noisy voter model enhances consensus formation
Jaume Llabrés, Sara Oliver-Bonafoux, Celia Anteneodo +1
We investigate the effects of aging in the noisy voter model considering that the probability to change states decays algebraically with age , defined as the time elapsed since…

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…
