From conformal invariance to quasistationary states
(Institute of Physics - IOPBristol, 2011-09)
In a conformal invariant one-dimensional stochastic model, a certain nonlocal perturbation takes the system to a new massless phase of a special kind. The ground-state of the system is an adsorptive state. Part of the ...
Critical behavior of a contact process with aperiodic transition rates
(IOP PUBLISHING LTD, 2008)
We performed Monte Carlo simulations to investigate the steady-state critical behavior of a one-dimensional contact process with an aperiodic distribution of rates of transition. As in the presence of randomness, spatial ...
Aging and stationary properties of non-equilibrium symmetrical three-state models
(IOP PUBLISHING LTD, 2011)
We consider a non-equilibrium three-state model whose dynamics is Markovian and displays the same symmetry as the three-state Potts model, i.e. the transition rates are invariant under the cyclic permutation of the states. ...
Mean-field analysis of the majority-vote model broken-ergodicity steady state
(Institute of Physics - IOPBristol, 2012-06)
We study analytically a variant of the one-dimensional majority-vote model in which the individual retains its opinion in case there is a tie among the neighbors' opinions. The individuals are fixed at the sites of a ring ...
Exact correlation functions in particle-reaction models with immobile particles
(IOP PUBLISHING LTDBRISTOL, 2012)
Exact results on particle densities as well as correlators in two models of immobile particles, containing either a single species or else two distinct species, are derived. The models evolve following a descent dynamics ...
