The four-state Potts model is sometimes known as the Ashkin–Teller model, after Julius Ashkin and Edward Teller, who considered an equivalent model in 1943. The Potts model is related to, and generalized by, several other models, including the XY model , the Heisenberg model and the N-vector model .
Jan 25, 2023 · The Ashkin-Teller model is a pair of interacting Ising models and has two parameters: J is a coupling constant in the Ising models and U describes the strength of the interaction between them. In the ferromagnetic case J, U > 0 on the square lattice, we establish a complete phase diagram conjectured in physics in 1970s (by Kadanoff and Wegner ...

Sep 13, 2022 · There seems to be two different definitions of the so-called "Ashkin-Teller model", and I'm not sure which one is the one assumed by physicists (or which one is of more interest). First, in wikipedia, the model seems to be defined as the 4-state clock model.
Abstract: The Ashkin–Teller model is a pair of interacting Ising models and has two parameters: J is a coupling constant in the Ising models and U describes the strength of the interaction between them.
Mar 9, 2024 · We map the quantum FFB model to a classical equivalent and then to the Ashkin-Teller model in order to trace the origin of emergent criticality, and hence to shed light on its possible...
