Functional RG approach to the Potts model
The critical behavior of the (n + 1)-states Potts model in d-dimensions is studied with functional renormalization group techniques. We devise a general method to derive β-functions for continuous values of d and n and we ...
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 ...
On the asymptotic critical behavior of Fe17Dy2, Fe17Ho2 and Fe17Er2 single crystals
(Akademie Verlag GmbhBerlinAlemanha, 1997)
Site-bond percolation on simple cubic lattices: Numerical simulation and analytical approach
(IOP Publishing, 2016-09)
The site-percolation problem on simple cubic lattices has been studied by means of numerical simulation and analytical calculations based on exact counting of configurations on finite cells. Motivated by considerations of ...
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. ...
A new scale-invariant ratio and finite-size scaling for the stochastic susceptible-infected-recovered model
(IOP PUBLISHING LTD, 2011)
The critical behavior of the stochastic susceptible-infected-recovered model on a square lattice is obtained by numerical simulations and finite-size scaling. The order parameter as well as the distribution in the number ...
A conformal invariant growth model
(IOP PUBLISHING LTD, 2010)
We present a one-parameter extension of the raise and peel one-dimensional growth model. The model is defined in the configuration space of Dyck (RSOS) paths. Tiles from a rarefied gas hit the interface and change its ...
Nonlocal asymmetric exclusion process on a ring and conformal invariance
(Institute of Physics - IOPBristol, 2013-09)
We present a one-dimensional nonlocal hopping model with exclusion on a ring. The model is related to the Raise and Peel growth model. A nonnegative parameter u controls the ratio of the local backwards and nonlocal forwards ...
Universality and criticality of a second-order granular solid-liquid-like phase transition
(American Physical Society, 2015)
We experimentally study the critical properties of the nonequilibrium solid-liquid-like transition that takes place in vibrated granular matter. The critical dynamics is characterized by the coupling of the density field ...
Critical phenomena in quasi-two-dimensional vibrated granular systems
(Amer Physical SOC, 2018)
The critical phenomena associated to the liquid-to-solid transition of quasi-two-dimensional vibrated granular systems is studied using molecular dynamics simulations of the inelastic hard sphere model. The critical ...
