Ashkin-Teller Model

The Ashkin-Teller model is a mathematical framework used in statistical physics to study phase transitions in materials. It extends the Ising model by considering two types of spins (magnetic moments) on a lattice, allowing for more complex interactions. This model helps researchers understand how local interactions between neighbors can lead to collective behavior, such as magnetism or the formation of ordered states. By analyzing these interactions, scientists gain insights into critical phenomena, like how materials change from solid to liquid, contributing to fields like condensed matter physics and materials science.
