On the gauge invariant boundary condition in open XXZ chains: SoV bases, elementary blocks and overlaps
G. Niccoli, V. Terras
We consider the open XXZ spin chain with unparallel boundary fields, in the special case in which the Vertex-IRF transform of the K-matrix labelling the boundary field at site 1 is…
On correlation functions of the open XYZ spin 1/2 chain with boundary fields related by a constraint
G. Niccoli, V. Terras
In this paper, we consider the quantum XYZ open spin-1/2 chain with boundary fields. We focus on the particular case in which the six boundary parameters are related by a single co…
Boundary overlap in the open XXZ spin chain
Charbel Abetian, Nikolai Kitanine, Veronique Terras
In this paper we compute the overlaps of the ground states for the open spin chains after a change of one of the boundary magnetic fields. It can be considered as the first step to…
The open XYZ spin 1/2 chain: Separation of Variables and scalar products for boundary fields related by a constraint
G. Niccoli, V. Terras
We consider the open XYZ spin chain with boundary fields. We solve the model by the new Separation of Variables approach introduced in arXiv:1904.00852. In this framework, the tran…
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…
