Spin operator matrix elements in the quantum Ising chain: fermion approach
N. Iorgov, V. Shadura, Yu. Tykhyy
Using some modification of the standard fermion technique we derive factorized formula for spin operator matrix elements (form-factors) between general eigenstates of the Hamiltoni…
Eigenvectors of Baxter-Bazhanov-Stroganov τ^{(2)}(t_q) model with fixed-spin boundary conditions
N. Z. Iorgov, V. N. Shadura, Yu. V. Tykhyy
The aim of this contribution is to give the explicit formulas for the eigenvectors of the transfer-matrix of Baxter-Bazhanov-Stroganov (BBS) model (N-state spin model) with fixed-s…
Asymptotics of correlation function of twist fields in two-dimensional lattice fermion model
Anatolij I. Bugrij, Vitalij N. Shadura
In two-dimensional lattice fermion model a determinant representation for the two-point correlation function of the twist field in the disorder phase is obtained. This field is def…
Duality in 2D Spin Models on Torus
A. I. Bugrij, V. N. Shadura
Method of derivation of the duality relations for two-dimensional Z(N)-symmetric spin models on finite square lattice wrapped on the torus is proposed. As example, exact duality re…
Duality of the 2D Nonhomogeneous Ising Model on the Torus
Anatolij I. Bugrij, Vitalij N. Shadura
Duality relations for the 2D nonhomogeneous Ising model on the finite square lattice wrapped on the torus are obtained. The partition function of the model on the dual lattice with…
