The quantum mechanics examples in this section model standard quantum-mechanical phenomena seen in intermediate and advanced courses. The material stresses time evolution of bound states (eigenstates, 2-state superpositions, and wave packets) and measurement (spin and bound-state systems) of quantum-mechanical systems. The programs depict the time-dependent quantum-mechanical wave function either by time evolving analytic energy eigenstate solutions (which correspond to several standard potentials), time evolving numerically-determined energy eigenstate solutions, or numerically time evolving an initial state. Although the programs presented here are distributed in Launcher packages that contain multiple programs and associated curricular material, they can also be be embedded into html pages for easy Internet-based distribution and quick browsing.
You are encouraged to download the following jar files to execute complete Launcher packages after you have become familiar with the programs in this section and subsection.

| ajp_reduced_hilbert.jar | Launcher package in support of the paper, "Numerical Time Development in Quantum Mechanics Using a Reduced Hilbert Space Approach," submitted to the American Journal of Physics. The package describes the suite of open source computer programs that numerically calculate, time evolve, and visualize arbitrary initial quantum-mechanical bound states. You may download the package using the link to the left or click here to navigate to the paper site and run via your web browser. |
| osp_qm_measurement.jar | Quantum mechanics exercises by Mario Belloni and Wolfgang Christian. These exercises focus on the measurement of energy, position, and momentum of a given quantum state. These states are either energy eigenstates, two-state superpositions, or localized wave packets. The multiple measurements can be made on a single state or single measurements can be made on identically prepared elements of an ensemble. Multiple exercises are combined in this jar file as a Launcher package. |
| osp_spins.jar | Quantum mechanics exercises by Mario Belloni and Wolfgang Christian. These exercises focus on the single and multiple measurement of an ensemble of spin-1/2 systems. In addition, these exercises also show the time evolution of spin states in an external magnetic field (spin precession). Multiple exercises are combined in this jar file as a Launcher package. |
| osp_qm_superposition.jar | Quantum mechanics exercises by Mario Belloni and Wolfgang Christian. These exercises focus on the time evolution of energy eigenstates, two-state superpositions, and localized wave packets. Multiple exercises are combined in this jar file as a Launcher package. |
| osp_quilt.jar | Quantum mechanics tutorial by Chandralekha Singh. these exercises focus on the time evolution eigenstates and superpositions. Multiple tutorial exercises are combined in this jar file as a Launcher package. |
