Computer implementation of the Kerov–Kirillov–Reshetikhin algorithm
Description
Abstract The Kerov–Kirillov–Reshetikhin (KKR) algorithm establishes a bijection between semistandard Weyl tableaux of the shape λ and weight μ and rigged string configurations of type ( λ , μ ) . This algorithm can be applied to Heisenberg magnetic chains and their generalisations by use of Schur–Weyl duality, and gives a way to classify all eigenstates of the chain in a methodological manner. Title of program: KKR algorithm Catalogue Id: AELQ_v1_0 Nature of problem The method of classification of all eigenstates and eigenvalues is given for the generalized model of the one-dimensional Heisenberg magnet consisting of N nodes.
