Main Document

QM Carpet Program 

written by Wolfgang Christian

The QM Carpet program displays the time evolution of the position-space wave function and the associated quantum-mechanical space-time diagram, the 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 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_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.
