Title:Three-dimensional Waves in Excitable Systems
Seminar:The Pritchard Lab Seminar
Speaker:Oliver Steinbock, Dept of Chemistry & Biochemistry, Florida State University
Abstract:
Excitable and oscillatory reaction-diffusion system can show rotating wave solutions. In spatially two-dimensional media, these vortices tend to be Archimedean spirals rotating around very small, inactive core regions. In the three-dimensional case, these regions can be described as space curves that either terminate in the system boundary or form a closed loops and knots. These "filaments" move and bend according to their local curvature and gradients in the associated rotation phase. My talk will review some of the most pertinent features of these patterns as well as their relevance to biological and biomedical systems. Moreover, I will discuss results obtained from experiments with the Belousov-Zhabotinsky reaction, show that phase evolution follows Burgers' equation, and describe ongoing research on vortex pinning.
