Critical Behavior of Mean-Field XY and Related Models

Kay Kirkpatrick, Tayyab Nawaz

Research output: Chapter in Book/Report/Conference proceedingChapter


We discuss spin models on complete graphs in the mean-field (infinite-vertex) limit, especially the classical XY model, the Toy model of the Higgs sector, and related generalizations. We present a number of results coming from the theory of large deviations and Stein’s method, in particular, Cramér and Sanov-type results, limit theorems with rates of convergence, and phase transition behavior for these models.
