If you like that simulation you might also like my own webGL Gross-Pitaevskii Equation (GPE) solver. It uses RK4 to simulate a 2D box of ultracold atoms undergoing Bose-Einstein Condensation. The GPE models a condensate as a single-particle quantum wavefunction with a non-linear form of the Schrödinger Equation, so you get some interesting behaviour from the non-linearity while the simulation remains computationally feasible. You can interact with the potential term by clicking and dragging inside the 2D box. https://georgestagg.github.io/webgl_gpe/ https://georgestagg.github.io/webgl_gpe/
