The Free Gaussian Wave Packet model simulates the time evolution of a free-particle Gaussian wave packet in position and k (momentum) space. The position-space and k-space (momentum-space) wave functions are depicted using three colors on the graph to depict the absolute square of the wave function, the real part of the wave function, and the imaginary part of the wave function. The user may change the wave packet's initial width, its initial average position, and its initial average k value (momentum).
The Free Gaussian Wave Packet model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_qm_free_gaussian.jar file will run the program if Java is installed.
Please note that this resource requires at least version 1.5 of Java (JRE).
