A bstract In this paper we first demonstrate explicitly that the new models of integrable
nearest-neighbour Hamiltonians recently introduced in PRL 125 (2020) 031604 [36] satisfy …

The spectral problem of the Heisenberg XXZ spin-1 2 chain on the segment is investigated
within a modified algebraic Bethe ansatz framework. We consider in this work the most …

The modified algebraic Bethe ansatz, introduced by Crampé and the author [8], is used to
characterize the spectral problem of the Heisenberg XXZ spin-1 2 chain on the segment with …

We study the matrix ansatz in the quantum group framework, applying integrable systems
techniques to statistical physics models. We start by reviewing the two approaches, and then …

In this paper, we prove the off-shell equation satisfied by the transfer matrix associated with
the XXZ spin-1 2 chain on the segment with two generic integrable boundaries acting on the …

We solve the longstanding problem of defining a functional characterization of the spectrum
of the transfer matrix associated with the most general spin-1/2 representations of the six …

This chapter describes a general scheme for constructing quantum integrable models within
the Quantum Inverse Scattering Method (QISM) framework. Much of what is described here …

A bstract We show that the scalar products of on-shell and off-shell Bethe vectors in the
algebralic Bethe ansatz solvable models satisfy a system of linear equations. We find …

A bstract We consider the action of the q-deformed Poincaré superalgebra on the massless
non-relativistic R-matrix in ordinary (undeformed) integrable AdS 2× S 2× T 6 type IIB …

A bstract In this paper we initiate the study of form factors for the massless scattering of
integrable AdS 2 superstrings, where the difference-form of the S-matrix can be exploited to …
