The Nonlinear lorenz light
Dynamics Laboratory


Welcome to the University of Miami Physics Departments Nonlinear Dynamics Laboratory Home page. NDL is a facility dedicated to experimental and theoretical study of nonlinear dynamics and chaos. Observations of real systems provides the basis for understanding how to avoid (or initiate) instabilities and chaotic oscillations.

We have reported on inert-gas plasmas at low fractional ionization, fluid droplet dynamics, electronic circuits, and computer simulations that all exhibit similar dynamics, namely transitions to chaos.

The theoretical understanding of these systems and their transitions to chaos is incomplete. As the physical processes are made evident, the theory is called upon to offer ever better descriptions of the rich physics found in the study of these nonlinear phenomena.

We hope you have as much fun looking at this material as we have generating it!
