Nonlinear Dynamics Image Gallery

  • Data
    • Poincaré section. This kind of graph is used by both theorists and experimenters to detect the onset of chaos in nonlinear systems. This section is from Professor Meurice's field theory projects.
    • Poincaré section from Professor Meurice, using the same theoretical example as in the other graph, but at a larger energy. The periodic solution, which is the center of the concentric curves of the upper part of the first graph, has become unstable and appears as scattered points.
  • Labs
    • Professor Skiff, right, with graduate student Ilker Uzun. They launch ion waves in a plasma, and detect them using laser-induced fluorescence. They examine their results for evidence of nonlinear processes such as three-wave mixing and chaos.
    • Professor Skiff, right, with group members, in the laser room that adjoins their plasma lab. A tunable dye laser has an adjustable wavelength, allowing experimenters to use the Doppler effect to measure how many ions are moving at a given velocity. This optical technique is their primary method of measurement.
    • Graduate student Ahmed Diallo in Professor Skiff's plasma lab. The most prominent features in the plasma device in the background are large electromagnet coils that produce a uniform magnetic field. This field confines the plasma and alters the propagation of the ion waves that are studied for their nonlinear interactions.
