From Dauger Research:
Atom in a Box is an application that aids in visualizing the Hydrogenic atomic orbitals, a prime and otherwise unwieldy example of quantum mechanics. Unlike other tools in this category, this program raytraces through a three-dimensional cloud density that represents the wavefunction's probability density and presents its results in real-time (up to 48 frames per second on the latest hardware). The user interface is very interactive and provides a wide degree of flexibility. It contains all 140 eigenstates up to the n=7 energy level and the allowed spectral transitions between those eigenstates. It also allows a state formed by a superposition of up to eight of those eigenstates allowing for over 3 trillion possible states. The program can display a wavefunction as a picture of a cloud, use color as phase, plot in red-cyan left/right for 3D glasses, and slice the wavefunction.
What's new in this version:
- Implemented a workaround for a bug in QDFlushPortBuffer under OS X 10.2 and 10.2.1 that made the animation a bit jerky.
- Thanks to Dr. Mark Winter of Sheffield College for catching the equation for the 6,0 angular momentum state. I had one too many cosines in the displayed equation, but the internal code, and therefore the pictures, were still correct.
- Updated the shareware address information.
