# B1: Kinetic Ising Model — Glauber Dynamics and Domain Coarsening
## Background
When a ferromagnetic system is rapidly cooled ("quenched") from a disordered high-temperature state to below its critical temperature, it does **not** instantly reach equilibrium. Instead, domains of aligned spins nucleate and grow over time — a process called **phase-ordering kinetics** or **domain coarsening**.
The 2D Ising model with single-spin-flip (Glauber) dynamics is the canonical system for studying this non-equilibrium phenomenon. The key theoretical prediction is the **Allen-Cahn growth law**: the characteristic domain size grows as
$$L(t) \propto t^{1/2}$$
for a non-conserved scalar order parameter (Model A dynamics).
