Main Document

QM Momentum Space Program 

written by Wolfgang Christian

The QM Momentum Space program displays the time evolution of the position-space wave function and the associated momentum-space wave 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 Momentum Space 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_fft.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.
