The affine Toda fields with boundary reflection
Takeo Kojima
We study the affine Toda fields with boundary reflection. Our approach is based on the free field approach. We construct free field realizations of the boundary sta…

Finite XXZ critical chain with double boundaries
T. Kojima
Finite XXZ chain with double boundaries is considered at critical regime . We construct the eigenvectors of finite Hamiltonian by means of vertex operators and the quasi-bo…

Dynamical Correlation Functions for an Impenetrable Bose gas with open boundary conditions
T. Kojima
We study the time and temperature dependent correlation functions for an impenetrable bose gas with open boundary conditions. We derive the Fredholm determinant formulae for the co…
