🧲 Ising Model — Temperature & Critical Point (2D)

Interactive 2D Ising model on Canvas2D. A real Metropolis-Hastings Monte Carlo lattice of ±1 spins with a live temperature slider crossing the critical point Tc≈2.269, showing the ferromagnetic phase transition in magnetisation and energy.

⚙ Under the hood

A Canvas2D companion to the 3D Ising model: the same real two-dimensional lattice of up/down spins and Metropolis-Hastings Monte Carlo update rule, focused on sweeping the temperature slider across the critical point Tc ≈ 2.269 J/kB. Watch the average magnetisation collapse as ordered spin domains dissolve into disorder above the critical temperature.
