Content, Learning Outcome and Preconditions

Content

This module provides an introduction to self-organization and pattern formation in spatially extended systems. After a motivation in which the universality of the observed patterns and their unified mathematical description are elucidated, the basic mechanisms that lead to spatio-temporal self-organization are discussed. We mainly focus on reaction-diffusion systems. The phenomena considered are ordered according to their complexity. First traveling waves in one-component bistable systems are explored, then pulses and spiral waves in excitable systems are discussed. Subsequently, we study the formation of Turing structures in spatially one and two-dimensional systems. Finally, oscillatory dynamics is considered. Here we begin by looking at an ensemble of globally coupled oscillators, elucidating the so-called Kuramoto transition from incoherent behavior to synchronized oscillations in detail, and then discuss synchronization behavior of oscillatory networks in a general context. Thereafter, the complex Ginzburg-Landau equation as prototypical equation for diffusively coupled oscillatory media is introduced, and the transition to spatio-temporal chaos investigated.

Learning Outcome

After participation in the Module the student is able to

  1. understand the basic mechanisms that lead to patterns and cooperative phenomena in dissipative systems far from the thermodynamic equilibrium
  2. explain the universal laws leading to pattern formation in reaction-diffusion systems in the bistable excitable and oscillatory regime with prototypical models
  3. explain the origin of synchronization phenomena in coupled oscillatory networks
  4. perform simulations of reaction-diffusion system and classify the observed patterns.
