Ground-state energies of the open and closed p + ip-pairing models from the Bethe Ansatz
Nuclear Physics B, 2018 Using the exact Bethe Ansatz solution, we investigate methods for calculating the ground-state energy for the p+ip-pairing Hamiltonian. We first consider the Hamiltonian isolated from its environment (closed model) through two forms of Bethe Ansatz ...

The Bethe-Ansatz approach to the N $$ \mathcal{N} $$ = 4 superconformal index at finite rank
Journal of High Energy Physics, 2021 We investigate the Bethe-Ansatz approach to the superconformal index of N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills with SU(N) gauge group in the context of finite rank, N.

On the Bethe states of the one-dimensional supersymmetric t − J model with generic open boundaries
Journal of High Energy Physics, 2017 By combining the algebraic Bethe ansatz and the off-diagonal Bethe ansatz, we investigate the supersymmetric t − J model with generic open boundaries. The eigenvalues of the transfer matrix are given in terms of an inhomogeneous T − Q relation, and the ...

Bethe ansatz and isomondromy deformations [PDF]
Theoretical and Mathematical Physics, 2009 We study symmetries of the Bethe equations for the Gaudin model appeared naturally in the framework of the geometric Langlands correspondence under the name of Hecke operators and under the name of Schlesinger transformations in the theory of isomonodromic deformations, and particularly in the theory of Painlevé transcendents.

Introduction to the Bethe Ansatz I
Computers in Physics, 1997 The Bethe ansatz for the one-dimensional s=1/2 Heisenberg ferromagnet is introduced at an elementary level. The presentation follows Bethe's original work very closely. A detailed description and a complete classification of all two-magnon scattering states and two-magnon bound states are given for finite and infinite chains. The paper is designed as a

Spectrum of the quantum integrable D 2 2 $$ {D}_2^{(2)} $$ spin chain with generic boundary fields
Journal of High Energy Physics, 2022 Exact solution of the quantum integrable D 2 2 $$ {D}_2^{(2)} $$ spin chain with generic integrable boundary fields is constructed. It is found that the transfer matrix of this model can be factorized as the product of those of two open staggered ...

ALGEBRAIC ASPECTS OF THE BETHE ANSATZ [PDF]
International Journal of Modern Physics A, 1995 In this article an introduction to the algebraic aspects of the Bethe ansatz is given. The applications to the seminal spin 1/2 XXX model are discussed in detail and the generalization to higher spin as well as XXZ and the lattice sine-Gordon model are indicated. The origin of quantum groups and their appearance in CFT models are explained.
