Coarsening of three-dimensional grains in crystals, or bubbles in dry foams, tends towards a universal, statistically scale-invariant regime
(2006) [Journal article]We perform extensive Potts model simulations of three-dimensional dry foam coarsening. Starting with 2.25 million bubbles, we have enough statistics to fulfill the three constraints required for the study of statistical ... -
Curvature-driven coarsening in the two-dimensional Potts model
(2010) [Journal article]We study the geometric properties of polymixtures after a sudden quench in temperature. We mimic these systems with the q-states Potts model on a square lattice with and without weak quenched disorder, and their evolution ... -
Domain-size heterogeneity in the Ising model : geometrical and thermal transition
(2015) [Journal article]A measure of cluster size heterogeneity (H), introduced by Lee et al. [Phys. Rev. E 84, 020101 (2011)] in the context of explosive percolation, was recently applied to random percolation and to domains of parallel spins ... -
Geometrical properties of the Potts model during the coarsening regime
(2012) [Journal article]We study the dynamic evolution of geometric structures in a polydegenerate system represented by a q-state Potts model with nonconserved order parameter that is quenched from its disordered into its ordered phase. The ... -
Growth laws and self-similar growth regimes of coarsening two-dimensional foams : transition from dry to wet limits
(2012) [Journal article]We study the topology and geometry of two-dimensional coarsening foam with an arbitrary liquid fraction. To interpolate between the dry limit described by von Neumann’s law and the wet limit described by Marqusee’s equation, ... -
Kosterlitz-Thouless and Potts transitions in a generalized XY model
(2014) [Journal article]We present extensive numerical simulations of a generalized XY model with nematic-like terms recently proposed by Poderoso et al. [Phys. Rev. Lett. 106, 067202 (2011)]. Using finite size scaling and focusing on the q = 3 ... -
Modeling oil–water separation with controlled wetting properties
(2021) [Journal article]Several oil–water separation techniques have been proposed to improve the capacity of cleaning water. With the technological possibility of producing materials with antagonist wetting behavior, for example, a substrate ...
