Research In Excitable Media
Matthew Strain
and I have looked at how transients and chaos scale with
system size for a two-dimensional two-field model of an excitable
media that has been studied previously because of the occurrence
of spatiotemporal chaos. The model was developed in the analysis
of heterogeneous catalysis on a metal surface.
Elizabeth Cherry
and I have investigated two topics related to
excitable media:
-
Improved numerical methods for simulating excitable media,
including a comparison of explicit versus implicit time
integration methods, and the applications of adaptive
meshing to 2d and 3d simulations.
-
Mapping out the basins of attraction of complex dynamical
states in semi-quantitative models of heart physiology. This
includes the problem of initiation, how filaments or spirals
are created by physiologically motivated initial conditions
such as stimulation by an electrode.
