The QM Momentum Carpet program displays the time evolution of the position-space wave function and the associated quantum-mechanical momentum-time diagram, the momentum-space quantum carpet. The default wave function is a Gaussian wave packet in an infinite square well. Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item.
QM Momentum Carpet 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_momentun_carpet.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.
