Dense loops, supersymmetry, and Goldstone phases in two dimensions.
Physical review letters, no. 9 (2003): 090601-090601
Loop models in two dimensions can be related to O(N) models. The low-temperature dense-loops phase of such a model, or of its reformulation using a supergroup as symmetry, can have a Goldstone broken-symmetry phase for N<2. We argue that this phase is generic for -2< N <2 when crossings of loops are allowed, and distinct from the model of...更多
