Degeneration of the Elliptic Algebra and Form Factors in the sine-Gordon Theory
Hitoshi Konno
Following the work with Jimbo and Miwa, we introduce a certain degeneration of the elliptic algebra and its boson realization. We investigate its rational…
Massless Model and Degeneration of the Elliptic Algebra
Michio Jimbo, Hitoshi Konno, Tetsuji Miwa
We consider an algebraic structure of the model in the gapless regime. We argue that a certain degeneration limit of the elliptic algebra is a relev…
Dynamical Correlation Functions and Finite-size Scaling in Ruijsenaars-Schneider Model
Hitoshi Konno
The trigonometric Ruijsenaars-Schneider model is diagonalized by means of the Macdonald symmetric functions. We evaluate the dynamical density-density correlation function and the…
Integrable Four-Fermi Models with a Boundary and Boson-Fermion Duality
Takeo Inami, Hitoshi Konno, Yao-Zhong Zhang
Construction of integrable field theories in space with a boundary is extended to fermionic models. We obtain general forms of boundary interactions consistent with integrability o…
Relativistic Calogero-Sutherland Model: Spin Generalization, Quantum Affine Symmetry and Dynamical Correlation Functions
Hitoshi Konno
Spin generalization of the relativistic Calogero-Sutherland model is constructed by using the affine Hecke algebra and shown to possess the quantum affine symmetry $\uqglt$. The sp…
Difference Equations in Spin Chains with a Boundary
Michio Jimbo, Rinat Kedem, Hitoshi Konno +2
Correlation functions and form factors in vertex models or spin chains are known to satisfy certain difference equations called the quantum Knizhnik-Zamolodchikov equations. We fin…
XXZ chain with a boundary
M. Jimbo, R. Kedem, T. Kojima +2
The $\XXZ$ spin chain with a boundary magnetic field is considered, using the vertex operator approach to diagonalize the Hamiltonian. We find explicit bosonic formulas for the…
Integrable XYZ Spin Chain with Boundaries
Takeo Inami, Hitoshi Konno
We consider a general class of boundary terms of the open XYZ spin-1/2 chain compatible with integrability. We have obtained the general elliptic solution of -matrix obeying the…

Hitoshi Konno
Using free field representation of quantum affine algebra , we investigate the structure of the Fock modules over . The analisys is based…
Coset Conformal Field Theory and Topological Minimal Model on Higher Genus Riemann Surface
Hitoshi Konno
We consider the Feigin-Fuchs-Felder formalism of the coset minimal conformal field theory and extend it to higher genus. We investigate a double…
