Example dynamic structure factor
Dynamic structure factor S(q,w) and dispersion curve inset for the Heisenberg ferromagnet on the simple cubic lattice with L20 at T 0.4 T c. The momentum transfer is in the 100 direction, that is, q (q,0,0), and the Brillouin zone boundary is at q.
The Dynamic Structure Factor (S(Q,ω)) is like a movie of how atoms move in a material. Instead of just knowing where atoms are, it tells us how they move together over time:
