Stochastic approach to epidemic spreading
Tânia Tomé, Mário J. de Oliveira
We analyze four models of epidemic spreading using a stochastic approach in which the primary stochastic variables are the numbers of individuals in each class. The stochastic appr…
Entropy production in linear Langevin systems
Gabriel T. Landi, Tânia Tomé, Mario J. de Oliveira
We study the entropy production rate in systems described by linear Langevin equations, containing mixed even and odd variables under time reversal. Exact formulas are derived for…
Critical properties of the susceptible-exposed-infected model on a square lattice
Alexander H. O. Wada, Tânia Tomé, Mário J. de Oliveira
The critical properties of the stochastic susceptible-exposed-infected model on a square lattice is studied by numerical simulations and by the use of scaling relations. In the pre…
Critical behavior in lattice models with two symmetric absorbing state
Áttila L. Rodrigues, Christophe Chatelain, Tânia Tomé +1
We analyze nonequilibrium lattice models with up-down symmetry and two absorbing states by mean-field approximations and numerical simulations in two and three dimensions. The phas…
Exact correlation functions in particle-reaction models with immobile particles
Christophe Chatelain, Malte Henkel, Mário J. De Oliveira +1
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 mo…
Aging and stationary properties of non-equilibrium symmetrical three-state models
Christophe Chatelain, Tânia Tomé, Mario J. De Oliveira
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…
