Glauber Dynamics — Kinetic Ising Model

Single spin-flip kinetics at temperature T. Watch magnetic domains coarsen as t grows. Domain size scales as L ~ t1/2 (Model A universality class).

Tc (2D) = 2.269
Glauber rate:
w(σᵢ→−σᵢ) = ½[1 − σᵢ tanh(βΣⱼσⱼ)]

Below Tc: domains grow
Above Tc: disordered (paramagnetic)

Domain size L(t) ~ t1/2
