摘要

The role of the ?_1-norm in the Yang-Baxter system has been studied through Wigner's D-functions, where ?_1-norm means ∑_i|C_i| for |Ψ> = ∑_iC _i|ψ_i> with |ψ_i> being the orthonormal basis. It is shown that the existing two types of braiding matrices, which can be viewed as particular solutions of the Yang-Baxter equation (YBE) with different spectral parameters can be unified in the 2D YBE. We prove that the maximum of the ?_1-norm is connected with the maximally entangled states and topological quantum field theory with two-component anyons, while the minimum leads to the deformed permutation related to the familiar integrable models.
