This software is a Java-based simulation tool that enables users to observe periodic potentials in two dimensions while using quantum mechanics principles.
Upon opening the software, you'll immediately notice a graph displaying the particle's wave function at the top of the screen. The default potential consists of an array of rectangular square wells, and the positions of these wells are indicated by gray lines.
Moving down the screen, you'll see the particle's position and its corresponding band structure. The band structure is displayed as a dispersion curve, which shows the particle's energy versus the crystal momentum k. The energy bands are displayed as a background of gray, while the particle's energy is displayed as a red horizontal line.
Finally, below the dispersion curve, you'll find a graph showcasing the reciprocal lattice or "k-space." The colored dots match the colored lines within the band structure graph. To view a particular state, simply click on either the dispersion curve or k-space graph.
Overall, the 2-D Quantum Crystal software is an excellent way to explore and visualize particle behavior in a two-dimensional crystal.
