Study the position-space wave function with this application. 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.
