simulation of the Bar model
(Click on the figure to see a bigger version.) Simulation of the Bar model of a two-dimensional excitable medium consisting of carbon monoxide adsorbing to a platinum surface and being catalyzed to carbon dioxide, with some restructuring of the metal surface. Although the dynamics appears chaotic, a careful study by Matt Strain and Henry Greenside [Phys. Rev. Lett 80(11):2307-2309 (1998)] strongly suggests that all dynamics are transient, with an average transient time that grows exponentially with the size of the domain. This result may be relevant to the observation that the hearts of small mammals are less likely to enter spontaneously into a state of ventricular fibrillation.
