Temperature Correlation Functions in the XXO Heisenberg Chain
نویسندگان
چکیده
Space and time dependent correlation functions in the Heisenberg XX0 chain (in transverse magnetic field) are expressed in terms of Fredholm determinants of linear integral operators at all temperatures. The obtained expression allows useful computation of spectral shapes. Moreover, these determinant expressions allow to evaluate the asymptotic behaviour of correlation functions.

Correlation Functions in the XXO Heisenberg Chain and their Relations with Spectral Shapes
The spectral shape of one dimensional systems (describing for instance the behaviour of Frenkel excitons) is approached through the exactly solvable model of XXO Heisenberg quantum spin chain in a transverse magnetic field. Some results for finite size chains concerning 2N-point correlators are presented in details. In particular the finite lattice, finite temperature 2-point correlators are ex...

We calculate the low temperature asymptotics of a function γ that generates the temperature dependence of all static correlation functions of the isotropic Heisenberg chain.
متن کاملString correlation functions of the spin-1/2 Heisenberg XXZ chain
We calculate certain string correlation functions, originally introduced as order parameters in integer spin chains, for the spin-1/2 XXZ Heisenberg chain at zero temperature and in the thermodynamic limit. For small distances, we obtain exact results from Bethe Ansatz and exact diagonalization, whereas in the large-distance limit, field-theoretical arguments yield an asymptotic algebraic decay...
متن کاملCorrelation functions of the spin-1/2 anti-ferromagnetic Heisenberg chain: exact calculation via the generating function
Analytical expressions of some of the spin-spin correlation functions up to eight lattice sites for the spin-1/2 anti-ferromagnetic Heisenberg chain at zero temperature without magnetic field are obtained. The key object of our method is the generating function of two-point spin-spin correlators, whose functional relations are derived from those for general inhomogeneous correlation functions p...
متن کاملCorrelation functions of the higher spin XXX chains
Using the Algebraic Bethe Ansatz we consider the correlation functions of the integrable higher spin chains. We apply a method recently developed for the spin 12 Heisenberg chain, based on the solution of the quantum inverse problem. We construct a representation for the correlation functions on a finite chain for arbitrary spin. Then we show how the string solutions of the Bethe equations can ...
