Glauber Dynamics — Ising Model Relaxation

Single-spin-flip Markov chain for the Ising model; at T_c, relaxation time diverges as a power law (critical slowing down).

Temperature T/Tc: Sweeps/frame:

Glauber (1963) defined spin-flip dynamics with acceptance rate P(flip) = 1/(1+exp(2βΔE)). Critical temperature for 2D Ising: Tc = 2J/ln(1+√2) ≈ 2.269J. Near Tc, correlation time ξ_t ~ |T-Tc|^{-zν}, z≈2.17 (dynamic universality class).
