Herding and idiosyncratic choices: Nonlinearity and aging-induced transitions in the noisy voter model
Oriol Artime, Adrián Carro, Antonio F. Peralta +3
We consider the herding to non-herding transition caused by idiosyncratic choices or imperfect imitation in the context of the Kirman Model for financial markets, or equivalently t…

Aging-induced continuous phase transition
Oriol Artime, Antonio F. Peralta, Raúl Toral +2
Aging is considered as the property of the elements of a system to be less prone to change states as they get older. We incorporate aging into the noisy voter model, a stochastic m…

First-passage distributions for the one-dimensional Fokker-Planck equation
Oriol Artime, Nagi Khalil, Raul Toral +1
We present an analytical framework to study the first-passage (FP) and first-return (FR) distributions for the broad family of models described by the one-dimensional Fokker-Planck…
