QM Position Expectation Value Program
written by Wolfgang Christian
The QM Position Expectation Value program displays the time evolution of the position-space wave function and the associated position expectation value.  The default wave function is a two-state superposition of infinite square well states.  Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item.

QM Position Expectation Value 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_expectation_x.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.
