Form Factors in the sine-Gordon Theory
Following the work with Jimbo and Miwa[1], we introduce a certain degeneration of the elliptic algebra Aq,p ( ŝl2 ) and its boson realization. We investigate its rational limit. The limit is the central extension of the Yangian double DY (sl2) at level one. We give a new boson realization of it. Based on these algebras, we reformulate the Smirnov’s form factor bootstrap approach to the sine-Gor...
متن کاملOn noncommutative sinh-Gordon equation
We give a noncommutative extension of sinh-Gordon equation. We generalize a linear system and Lax representation of the sinh-Gordon equation in noncommutative space. This generalization gives a noncommutative version of the sinh-Gordon equation with extra constraints, which can be expressed as global conserved currents. PACS: 11.10.Nx, 02.30.Ik
متن کاملBoundary form factors of the sinh-Gordon model with Dirichlet boundary conditions at the self-dual point
In this manuscript we present a detailed investigation of the form factors of boundary fields of the sinh-Gordon model with a particular type of Dirichlet boundary condition, corresponding to zero value of the sinh-Gordon field at the boundary, at the self-dual point. We follow for this the boundary form factor program recently proposed by Z. Bajnok, L. Palla and G. Takacs [1], extending the an...
متن کاملParametric holomorphy? Triviality versus Duality in Sinh-Gordon
Suppose a regularised functional integral depends holomorphically on a parameter that receives only a finite renormalization. Can one expect the correlation functions to retain the analyticity in the parameter after removal of the cutoff(s)? We examine the issue in the Sinh-Gordon theory by computing the intrinsic 4-point coupling as a function of the Lagrangian coupling β. Drawing on the conje...
متن کاملReflection factors and a two-parameter family of boundary bound states in the sinh-Gordon model
The investigation of boundary breather states of the sinh-Gordon model restricted to a half-line is revisited. Properties of the classical boundary breathers for the twoparameter family of integrable boundary conditions are reviewed and extended. The energy spectrum of the quantized boundary states is computed, firstly by using a bootstrap technique and, subsequently using a WKB approximation. ...
