New results in the XXZ open spin chain
Pascal Baseilhac
In this review, I describe a recent approach based on the representation theory of the Onsager algebra which is used to derive exact results for the XXZ open spin chain. The co…
The q-deformed analogue of the Onsager algebra: Beyond the Bethe ansatz approach
Pascal Baseilhac
The spectral properties of operators formed from generators of the q-Onsager non-Abelian infinite dimensional algebra are investigated. Using a suitable functional representation,…
An integrable structure related with tridiagonal algebras
Pascal Baseilhac
The standard generators of tridiagonal algebras, recently introduced by Terwilliger, are shown to generate a new (in)finite family of mutually commuting operators which extends the…
Deformed Dolan-Grady relations in quantum integrable models
Pascal Baseilhac
A new hidden symmetry is exhibited in the reflection equation and related quantum integrable models. It is generated by a dual pair of operators $\{\textsf{A}, \textsf{A}^*\}\in{\c…
N=2 boundary supersymmetry in integrable models and perturbed boundary conformal field theory
P. Baseilhac, K. Koizumi
Boundary integrable models with N=2 supersymmetry are considered. For the simplest boundary N=2 superconformal minimal model with a Chebyshev bulk perturbation we show explicitly h…
On the third level descendent fields in the Bullough-Dodd model and its reductions
P. Baseilhac, M. Stanishkov
Exact vacuum expectation values of the third level descendent fields in the Bullough-Dodd model are proposed. By performing quantum group…
