Lifespan method as a tool to study criticality in absorbing-state phase transitions
(Physical Review E, 2018)
Phase transitions with infinitely many absorbing states in complex networks
(Physical Review E, 2018)
Continuous and discontinuous absorbing-state phase transitions on Voronoi-Delaunay random lattices
(Physical Review E, 2018)
Activated Random Walks on Zd*
(Institute of Mathematical Statistics, 2020-10)
Some stochastic systems are particularly interesting as they exhibit critical behavior without fine-tuning of a parameter, a phenomenon called self-organized criticality. In the context of driven-dissipative steady states, ...
Dependence of the crossover exponent with the diffusion rate in the generalized contact process model
(Sociedade Brasileira de Física, 2008)
We study how the crossover exponent, phi, between the directed percolation (DP) and compact directed percolation (CDP) behaves as a function of the diffusion rate in a model that generalizes the contact process. Our ...
Avalanches in Critical Activated Random Walks
(Birkhäuser, 2021)
We consider Activated Random Walks on ℤ with totally asymmetric jumps and critical particle density, with different time scales for the progressive release of particles and the dissipation dynamics. We show that the ...
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 ...
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. ...
Dynamics of a first-order transition to an absorbing state
(American Physical Society, 2014)
Agranular system confined in a quasi-two-dimensional box that is vertically vibrated can transit to an absorbing
state in which all particles bounce vertically in phase with the box, with no horizontal motion. In principle, ...
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 ...
