The Complex Ginzburg-Landau Equation in the Presence of Walls and Corners
Victor M. Eguiluz, Emilio Hernandez-Garcia, Oreste Piro
We investigate the influence of walls and corners (with Dirichlet and Neumann boundary conditions) in the evolution of twodimensional autooscillating fields described by the comple…
An entropy-driven noise-induced phase transition
M. Ibanes, J. Garcia-Ojalvo, R. Toral +1
We introduce a class of exactly solvable models which exhibit an ordering noise-induced phase transition driven by an entropic mechanism. In contrast with previous studies, order d…
Dynamics and Scaling of Noise-Induced Domain Growth
M. Ibanes, J. Garcia-Ojalvo, R. Toral +1
The domain growth processes originating from noise-induced nonequilibrium phase transitions are analyzed, both for non-conserved and conserved dynamics. The existence of a dynamica…
Quasiperiodic Patterns in Boundary-Modulated Excitable Waves
Irene Sendiña-Nadal, Vicente Pérez-Muñuzuri, Víctor M. Eguíluz +2
We investigate the impact of the domain shape on wave propagation in excitable media. Channelled domains with sinusoidal boundaries are considered. Trains of fronts generated perio…
Low-dimensional dynamical system model for observed coherent structures in ocean satellite data
Cristobal Lopez, Emilio Hernandez-Garcia
The dynamics of coherent structures present in real-world environmental data is analyzed. The method developed in this Paper combines the power of the Proper Orthogonal Decompositi…
Population dynamics advected by chaotic flows: a discrete-time map approach
Cristobal Lopez, Emilio Hernandez-Garcia, Oreste Piro +2
A discrete-time model of reacting evolving fields, transported by a bidimensional chaotic fluid flow, is studied. Our approach is based on the use of a Lagrangian scheme where {\it…
