The order-disorder transition takes place when the …
WebSep 20, 2024 · That is, if we write the energy as a sum over sites, then we have cross-terms because the sites interact with each other, but if we take the Fourier Transform, we can instead write the energy as a sum over non-interacting modes. In terms of normal modes, the Gaussian model is just a bunch of uncoupled harmonic oscillators.
