Description
2-D Quantum Crystal is a free and Java based physics simulation created so that one can easily the behavior of a particle in a two-dimensional crystal (or periodic potential).
At the top of the applet you will see a graph of the particle's wave function. By default, the potential is an array of rectangular square wells; the gray lines indicate the positions of the wells.
Below the particle's position you will see its band structure, displayed as a dispersion curve; this is a graph of energy versus the crystal momentum k, with the energy bands shown as gray in the background. The particle's energy is shown as a red horizontal line.
Below the dispersion curve is a graph of the reciprocal lattice, or "k-space". The colored dots correspond to the colored lines in the band structure graph.
To view a state, click on either the dispersion curve or the k-space graph.
