Something I found interesting when running analysis on Ising models; if you do an FFT (2 dimensional) on it, you get what amounts to a wavey star-like blob in the middle (assuming you center the lowest frequencies) If that blob is a small dot, or even nothing at all; you have a stable system, and if you have a sprawling kind of wavey response-pattern, then your lattice is gone critical. (Also it looks cool, and it’s quick to diagnose by a glance.) |
