Potts model - Wikipedia The Potts model consists of spins that are placed on a lattice; the lattice is usually taken to be a two-dimensional rectangular Euclidean lattice, but is often generalized to other dimensions and lattice structures
[2503. 23758] Exact solution of the frustrated Potts model with next . . . The one-dimensional (1D) J1 - J2 q -state Potts model is solved exactly for arbitrary q by analytically block-diagonalizing the original q2 ×q2 transfer matrix into a simple 2 × 2 maximally symmetric subspace, based on using OpenAI's reasoning model o3-mini-high to exactly solve the q = 3 case
