The QM Momentum Space program displays the time evolution of the position-space wave function and the associated momentum-space wave function. 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. The default wave function is a Gaussian wave packet in a harmonic oscillator. 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.
