Circular Well Superposition Model
written by Wolfgang Christian
The Circular Well Superposition simulation displays the time evolution of the position-space wave function in an infinite 2D circular well.  The default configuration shows the first excited state with zero angular momentum.  Additional eigenstates can be added using a button in the eigenstate coefficient table. A description of the quantum system and eigenstates, with questions for the students, are included.

Circular Well Superpostion 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_qm_Superposition2DCircularWell.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.  Additional Open Source Physics programs for quantum mechanics are available.  They can be found by searching ComPADRE for Open Source Physics, OSP, or EJS.

Please note that this resource requires at least version 1.5 of Java.
