Multi-point correlation functions in the boundary XXZ chain at finite temperature
Karol K. Kozlowski, Véronique Terras
We consider multi-point correlation functions in the open XXZ chain with longitudinal boundary fields and in a uniform external magnetic field. We show that, at finite temperature,…

On correlation functions for the open XXZ chain with non-longitudinal boundary fields : the case with a constraint
G. Niccoli, V. Terras
This paper is a continuation of [1], in which a set of matrix elements of local operators was computed for the XXZ spin-1/2 open chain with a particular case of unparallel boundary…

Correlation functions for open XXZ spin 1/2 quantum chains with unparallel boundary magnetic fields
G. Niccoli, V. Terras
In this paper we continue our derivation of the correlation functions of open quantum spin 1/2 chains with unparallel magnetic fields on the edges; this time for the more involved…
