We consider a rational six vertex model on a rectangular lattice with boundary conditions
that generalize the usual domain wall type. We find that the partition function of the …

This paper is a continuation of [J. Phys. A: Math. Theor. 55, 405203 (2022)], in which a set of
matrix elements of local operators was computed for the XXZ spin-1/2 open chain with a …

We consider the XXZ spin-1/2 Heisenberg chain with antiperiodic boundary conditions. The
inhomogeneous version of this model can be solved by separation of variables, and the …

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 case …

The q-Racah polynomials are expressed in terms of certain ratios of scalar products of Bethe
states associated with Bethe equations of either homogeneous or inhomogeneous type …

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 …

We study the so (3) Gaudin model with general boundary K-matrix in the framework of the
algebraic Bethe ansatz. The off-shell action of the generating function of the so (3) Gaudin …

The intricacies of fundamental interactions between elementary particles or massive objects
are respectively understood within the framework of quantum physics (more specifically …
