Factorization of the finite temperature correlation functions of the XXZ chain in a magnetic field
Herman E. Boos, Frank Göhmann, Andreas Klümper +1
We present a conjecture for the density matrix of a finite segment of the XXZ chain coupled to a heat bath and to a constant longitudinal magnetic field. It states that the inhomog…
Fermionic basis for space of operators in the XXZ model
H. Boos, M. Jimbo, T. Miwa +2
In the recent study of correlation functions for the infinite XXZ spin chain, a new pair of anti-commuting operators was introduced. They act on the space of quasi-loc…
A recursion formula for the correlation functions of an inhomogeneous XXX model
H. Boos, M. Jimbo, T. Miwa +2
A new recursion formula is presented for the correlation functions of the integrable spin 1/2 XXX chain with inhomogeneity. It relates the correlators involving n consecutive latti…
New formulae for solutions of quantum Knizhnik-Zamolodchikov equations on level -4 and correlation functions
Hermann Boos, Vladimir Korepin, Feodor Smirnov
This paper is continuation of our previous papers hep-th/0209246 and hep-th/0304077 . We discuss in more detail a new form of solution to the quantum Knizhnik-Zamolodchikov equatio…
