Item Picture
written by Wolfgang Christian
The Eigenstate Superposition model illustrates the fundamental building blocks of one-dimensional quantum mechanics, the energy eigenfunctions  ψn(x) and energy eigenvalues En.  The user enters the expansion coefficients into a table and the simulation uses the superposition principle to construct and display a time-dependent wave function using either infinite square well (ISW) or simple harmonic oscillator (SHO) eigenfunctions.

The Eigenstate Superposition 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_Superposition.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).
