Matrix Coordinate Bethe Ansatz: Applications to XXZ and ASEP models

, 2011
18 pages.We present the construction of the full set of eigenvectors of the open ASEP and XXZ models with special constraints on the boundaries. The method combines both recent constructions of coordinate Bethe Ansatz and the old method of matrix Ansatz ...

Reflection Amplitudes of ADE Toda Theories and Thermodynamic Bethe Ansatz

, 2007
We study the ultraviolet asymptotics in affine Toda theories. These models are considered as perturbed non-affine Toda theories. We calculate the reflection amplitudes, which relate different exponential fields with the same quantum numbers.

Exact solution of the trigonometric SU(3) spin chain with generic off-diagonal boundary reflections

Nuclear Physics B, 2016
The nested off-diagonal Bethe ansatz is generalized to study the quantum spin chain associated with the SUq(3) R-matrix and generic integrable non-diagonal boundary conditions.

Quantum corrections to the string Bethe ansatz [PDF]

, 2006
One-loop corrections to the energy of semiclassical rotating strings contain both analytic and non-analytic terms in the 't Hooft coupling. Analytic contributions agree with the prediction from the string Bethe ansatz based on the classical S-matrix, but

Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring

Symmetry, Integrability and Geometry: Methods and Applications, 2010
We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has U_q(SU(3)) symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent from the finite-size scaling ...

Algebraic Bethe ansatz for the Temperley–Lieb spin-1 chain

Nuclear Physics B, 2016
We use the algebraic Bethe ansatz to obtain the eigenvalues and eigenvectors of the spin-1 Temperley–Lieb open quantum chain with “free” boundary conditions.

Riemann zeros as quantized energies of scattering with impurities

Journal of High Energy Physics
We construct an integrable physical model of a single particle scattering with impurities spread on a circle. The S-matrices of the scattering with the impurities are such that the quantized energies of this system, coming from the Bethe Ansatz equations,

Exact solution of a quantum integrable system associated with the G2 exceptional Lie algebra

Nuclear Physics B
A quantum integrable spin chain model associated with the G2 exceptional Lie algebra is studied. By using the fusion technique, the closed recursive relations among the fused transfer matrices are obtained.

Tensor-network analysis of root patterns in the XXX model with open boundaries

SciPost Physics
The string hypothesis of Bethe roots is a cornerstone in the thermodynamic analysis of quantum integrable systems, since it connects root configurations with physical quantities such as the ground-state energy, surface energy and excitation spectra.
