Phase ordering dynamics of cosmological models
Joao A. N. Filipe, Alan J. Bray
The ordering dynamics of the Higgs field is studied, using techniques inspired by the study of phase ordering in condensed matter physics, as a first step to understanding the evol…
Kinetics of fragmentation-annihilation processes
Joao A. N. Filipe, Geoff J. Rodgers
We investigate the kinetics of systems in which particles of one species undergo binary fragmentation and pair annihilation. In the latter, nonlinear process, fragments react at co…
Theoretical and numerical studies of chemisorption on a line with precursor layer diffusion
Joao A. N. Filipe, Geoff J. Rodgers
We consider a model for random deposition of monomers on a line with extrinsic precursor states. As the adsorbate coverage increases, the system develops non-trivial correlations d…
Phase Ordering Kinetics with External Fields and Biased Initial Conditions
J. A. N. Filipe, A. J. Bray, S. Puri
The late-time phase-ordering kinetics of the O(n) model for a non-conserved order parameter are considered for the case where the O(n) symmetry is broken by the initial conditions…
