Spontaneous magnetization of the XXZ Heisenberg spin-1/2 chain
A. G. Izergin, N. Kitanine, J. M. Maillet +1
Determinant representations of form factors are used to represent the spontaneous magnetization of the Heisenberg XXZ chain (Delta >1) on the finite lattice as the ratio of two det…
Temperature correlators in the two-component one-dimensional gas
A. G. Izergin, A. G. Pronko
The quantum nonrelativistic two-component Bose and Fermi gases with the infinitely strong point-like coupling between particles in one space dimension are considered. Time and temp…
Equal-time temperature correlators of the one-dimensional Heisenberg XY chain
A. G. Izergin, V. S. Kapitonov, N. A. Kitanine
Representations as determinants of dimensional matrices are obtained for equal-time temperature correlators of the anisotropic Heisenberg XY chain. These representation…
Correlation functions for a strongly correlated boson system
N. M. Bogoliubov, A. G. Izergin, N. A. Kitanine
The correlation functions for a strongly correlated exactly solvable one-dimensional boson system on a finite chain as well as in the thermodynamic limit are calculated explicitly.…
Correlators of the phase model
N. M. Bogoliubov, A. G. Izergin, N. A. Kitanine
We introduce the phase model on a lattice and solve it using the algebraic Bethe ansatz. Time-dependent temperature correlation functions of phase operators and the "darkness forma…
