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 ...

Preparing Bethe Ansatz Eigenstates on a Quantum Computer
PRX Quantum, 2021 Several quantum many-body models in one dimension possess exact solutions via the Bethe ansatz method, which has been highly successful for understanding their behavior.

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 ...

Massless AdS 2 scattering and Bethe ansatz [PDF]
Journal of High Energy Physics, 2017 We first analyse the integrable scattering theory describing the massless excitations of $AdS_2 \times S^2 \times T^6$ superstrings in the relativistic limit. The matrix part of the S-matrix is obtained in the BMN limit from the conjectured exact expression, and compared with known S-matrices with N=1 supersymmetry.

Bethe Ansatz and Bethe Vectors Scalar Products [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2010 An integral presentation for the scalar products of nested Bethe vectors for the quantum integrable models associated with the quantum affine algebra $U_q(\hat{\mathfrak{gl}}_3)$ is given. This result is obtained in the framework of the universal Bethe ansatz, using presentation of the universal Bethe vectors in terms of the total currents of a "new ...
