The Kicked Rotor model shows the dynamics of a rotating bar (rotor) that is kicked periodically. This model is also known as the standard map or the Chirikov-Taylor map. Each impulsive kick changes the angular momentum of the rotor instantaneously and the bar rotates uniformly between kicks. Clicking in the Poincare section sets the initial conditions of the rotor. You can examine and modify this simulation if you have EJS installed by right-clicking within the plot and selecting “Open EJS Model” from the pop-up menu item. The Kicked Rotor Dynamics model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_chaos_KickedRotorDynamics.jar file will run the program if Java is installed. EJS is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.
