Yang-Baxter equation for the asymmetric eight-vertex model.

چکیده
In this paper we study, in the manner of Baxter [R. J. Baxter Exactly Solved Models in Statistical Mechanics (Academic, New York, 1982)], the possible integrable manifolds of the asymmetric eight-vertex model. As expected, they occur when the Boltzmann weights are either symmetric or satisfy the free-fermion condition; but our analysis clarifies the reason why both manifolds need to share a universal invariant. We also show that the free-fermion condition implies three distinct classes of integrable models.

Random Matrix Theory and Classical Statistical Mechanics . I . Vertex Models
A connection between integrability properties and general statistical properties of the spectra of symmetric transfer matrices of the asymmetric eight-vertex model is studied using random matrix theory (eigenvalue spacing distribution and spectral rigidity). For Yang-Baxter integrable cases, including free-fermion solutions, we have found a Poissonian behavior, whereas level repulsion close to ...
متن کاملClassification of Eight-vertex Solutions of The Colored Yang-Baxter Equation
In this paper all eight-vertex type solutions of the colored Yang-Baxter equation dependent on spectral as well as color parameter are given. It is proved that they are composed of three groups of basic solutions, three groups of their degenerate forms and two groups of trivial solutions up to five solution transformations. Moreover, all non-trivial solutions can be classified into two types ca...
متن کاملYang-Baxterizations, Universal Quantum Gates and Hamiltonians
The unitary braiding operators describing topological entanglements can be viewed as universal quantum gates for quantum computation. With the help of the Brylinski’s theorem, the unitary solutions of the quantum Yang–Baxter equation can be also related to universal quantum gates. This paper derives unitary solutions of the quantum Yang–Baxter equation via Yang–Baxterization from the solutions ...
متن کاملUniversal Vertex-IRF Transformation for Quantum Affine Algebras
We construct a universal Vertex-IRF transformation between Vertex type universal solution and Face type universal solution of the quantum dynamical Yang-Baxter equation. This universal Vertex-IRF transformation satisfies the generalized coBoundary equation and is an extension of our previous work to the quantum affine Uq(A (1) r ) case. This solution has a simple Gauss decomposition which is co...
متن کاملStudying the Six-Vertex Model with the Yang-Baxter Equation
We study the six-vertex model, a two-dimensional model of ferroelectric solids, originally solved by Lieb [2] in a restricted case by Bethe ansatz. We construct the phase diagram by deriving and solving the Yang-Baxter equations [5], introduced in statistical physics by Baxter to generate integrable models in two-dimensions. We discuss the significance of the Yang-Baxter equation and comment on...
