The Rotor Model with spectral parameters and enumerations of Alternating Sign Matrices
Luigi Cantini 1 Journal of statistical mechanics-theory and experiment (2007) P08012 In this paper we study the Rotor Model of Martins and Nienhuis. After introducing spectral parameters, a combined use of integrability, polynomiality of the ground state wave function and a mapping into the fully-packed O(1)-model allows us to determine the sum rule and a family of […]
