Sticky grains do not change the universality class of isotropic sandpiles (2006)
Bonachela, Juan A., Ramasco, Jose J., Chate, Hugues, Dornic, Ivan, Munoz, Miguel A.
We revisit the sandpile model with ``sticky'' grains introduced by Mohanty and Dhar [Phys. Rev. Lett. {\bf 89}, 104303 (2002)] whose scaling properties were claimed to be in the universality class of...
Langevin description of critical phenomena with two symmetric absorbing states (2004)
Hammal, Omar Al, Chaté, Hugues, Dornic, Ivan, Muñoz, Miguel A.
On the basis of general considerations, we propose a Langevin equation accounting for critical phenomena occurring in the presence of two symmetric absorbing states. We study its phase diagram by...
Dornic, Ivan, Chate, Hugues, Munoz, M. A.
Efficient and accurate integration of stochastic (partial) differential equations with multiplicative noise can be obtained through a split-step scheme, which separates the integration of the...
Bona Fide Thermodynamic Temperature in Nonequilibrium Kinetic Ising Models (2003)
Sastre, Francisco, Dornic, Ivan, Chaté, Hugues
We show that a nominal temperature can be consistently and uniquely defined everywhere in the phase diagram of large classes of nonequilibrium kinetic Ising spin models. In addition, we confirm the...
Critical Coarsening without Surface Tension: the Voter Universality Class (2001)
Dornic, Ivan, Chaté, Hugues, Chave, Jérôme, Hinrichsen, Haye
We show that the two-dimensional voter model, usually considered to only be a marginal coarsening system, represents a broad class of models for which phase-ordering takes place without surface...
Critical Coarsening without Surface Tension: The Universality Class of the Voter Model (2001)
Chaté, Hugues, Chave, Jérôme, Dornic, Ivan, Hinrichsen, Haye
Analytical results for generalized persistence properties of smooth processes (2000)
Dornic, Ivan, Lemaître, Anaël, Baldassarri, Andrea, Chaté, Hugues
We present a general scheme to calculate within the independent interval approximation generalized (level-dependent) persistence properties for processes having a finite density of zero-crossings....
Mapping Self-Organized Criticality onto Criticality (1995)
Sornette, Didier, Johansen, Anders, Dornic, Ivan
We present a general conceptual framework for self-organized criticality (SOC), based on the recognition that it is nothing but the expression, “unfolded" in a suitable parameter space, of an...
