Entanglement and Berry Phase in a $9\times 9$ Yang-Baxter system

TL;DR

This paper constructs a unitary Yang-Baxter solution for a 9x9 system, demonstrating how it generates entangled states, analyzing the associated Hamiltonian, and exploring the Berry phase in this context.

Contribution

It introduces a new unitary R-matrix solution for a 9x9 Yang-Baxter system and links it to entanglement generation and Berry phase analysis.

Findings

Any two-qutrit entangled state can be generated using the R-matrix.

The Hamiltonian derived from the R-matrix can be expressed with SU(2) operators.

Berry phase is interpretable within this Yang-Baxter framework.

Abstract

A M-matrix which satisfies the Hecke algebraic relations is presented. Via the Yang-Baxterization approach, we obtain a unitary solution $\breve{R}(\theta,\varphi_{1},\varphi_{2})$ of Yang-Baxter Equation. It is shown that any pure two-qutrit entangled states can be generated via the universal $\breve{R}$-matrix assisted by local unitary transformations. A Hamiltonian is constructed from the $\breve{R}$-matrix, and Berry phase of the Yang-Baxter system is investigated. Specifically, for $ \varphi_{1}=\varphi_{2}$, 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.
