The QM Probability 2D program displays the time evolution of the two-dimensional probability density using color to represent its magnitude. The default wave function is a two-state superposition in the x (nx = 1,2) and y dimension (ny = 3,4) state in an infinite square well.  Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item.  

QM Probability 2D is one of 18 Open Source Physics programs that model time-dependent quantum mechanics using an energy eigenstate expansion.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the qm_probability_2d.jar file will run the program if Java is installed.  Other programs provide additional visualizations.  They can be found by searching ComPADRE for Open Source Physics, OSP, or Superposition.

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