Multiple reference states and complete spectrum of the Zn Belavin model with open boundaries
نویسندگان
چکیده
The multiple reference state structure of the Zn Belavin model with non-diagonal boundary terms is discovered. It is found that there exist n reference states, each of them yields a set of eigenvalues and Bethe Ansatz equations of the transfer matrix. These n sets of eigenvalues together constitute the complete spectrum of the model. In the quasi-classic limit, they give the complete spectrum of the corresponding Gaudin model. PACS: 75.10.Pq; 04.20.Jb; 05.50.+q

Exact solution of Z n Belavin model with open boundary condition
Zn Belavin model with open boundary condition is studied. The double-row transfer matrices of the model are diagonalized by algebraic Bethe ansatz method in terms of the intertwiner and the face-vertex correspondence relation. The eigenvalues and the corresponding Bethe ansatz equations are obtained. PACS: 03.65.Fd; 75.10.Jm; 05.30.-d
متن کاملA Survey on Precision of Nested Water Level Data Derived From Delft3D Model
One of the troublesome aspects of numerical modeling is to determine open boundaries for a model and to make sure that the boundary conditions employed at the open boundaries are compatible with physical processes being simulated within the interior of the model domain. In this investigation the accuracy of the water level data derived from delft3D employing nesting procedure were studied. Thes...
متن کاملBosonization of vertex operators for Zn symmetric Belavin model and its correlation functions
Based on the bosonization of vertex operators for A (1) n−1 face model by Asai,Jimbo, Miwa and Pugai,using vertex-face correspondence we obtain vertex operators for Zn symmetric Belavin model,which are constructed by deformed boson oscilllators. The correlation functions are also obtained.
متن کاملSmart City Reference Model: Interconnectivity for On-Demand User to Service Authentication
The Internet of Things and Services (IoTS) has encouraged the development of service provisioning systems in respect to Smart City topics. Most of them are operated as heterogeneous systems which limits end customers’ access and contradicts with IoTS principles. In this paper, we discuss and develop a reference model of an interconnected service marketplace ecosystem. The prototypical implement...
متن کاملDecentralized Model Reference Adaptive Control of Large Scale Interconnected Systems with Time-Delays in States and Inputs
This paper investigates the problem of decentralized model reference adaptive control (MRAC) for a class of large scale systems with time varying delays in interconnected terms and state and input delays. The upper bounds of the interconnection terms are considered to be unknown. Time varying delays in the nonlinear interconnection terms are bounded and nonnegative continuous functions and thei...
