Main Document

QM Wigner Program 

written by Wolfgang Christian

The QM Wigner program displays the time evolution of the position-space wave function and the associated quasi-probability distribution in phase space via the Wigner function.  The default wave function is a Gaussian wave packet in a harmonic oscillator.  Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item.  

QM Wigner 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_wigner.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.
