Abstract
A M-matrix which satisfies the Hecke algebraic relations is presented. Via the Yang-Baxterization approach, we obtain a unitary solution of Yang-Baxter Equation. It is shown that any pure two-qutrit entangled states can be generated via the universal -matrix assisted by local unitary transformations. A Hamiltonian is constructed from the -matrix, and Berry phase of the Yang-Baxter system is investigated. Specifically, for , the Hamiltonian can be represented based on three sets of SU(2) operators, and three oscillator Hamiltonians can be obtained. Under this framework, the Berry phase can be interpreted.
