Résumé |
Abstract:The Onsager algebra plays an important role in exactly solvable models. One of the most notable examples is the solution to the 2D classical Ising model using the Onsager algebra by Lars Onsager in 1944. I will explain the appearance of the Onsager algebra in various quantum lattice models, and report the recent results on the Onsager algebra as the symmetry of the 6-vertex model at root of unity values of anisotropy. The talk is based on a series of work in arXiv: 2606.25660, 2103.14569, 2012.10224 and work in progress. |
