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

open access: yesNuclear 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.

Finite size effects and the supersymmetric sine-Gordon models [PDF]

open access: yes, 2003
We propose nonlinear integral equations to describe the groundstate energy of the fractional supersymmetric sine-Gordon models. The equations encompass the N = 1 supersymmetric sine-Gordon model as well as the phi(id,id,adj) perturbation of the SU(2)(L ...

Riemann zeros as quantized energies of scattering with impurities

open access: yesJournal 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,

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

open access: yesSymmetry, 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 ...

Bukhvostov–Lipatov model and quantum-classical duality

open access: yesNuclear Physics B, 2018
The Bukhvostov–Lipatov model is an exactly soluble model of two interacting Dirac fermions in 1+1 dimensions. The model describes weakly interacting instantons and anti-instantons in the O(3) non-linear sigma model. In our previous work [arXiv:1607.04839]

Scalar products of Bethe vectors in the generalized algebraic Bethe ansatz [PDF]

open access: yes, 2023
We consider an $XYZ$ spin chain within the framework of the generalized algebraic Bethe ansatz. We study scalar products of the transfer matrix eigenvectors and arbitrary Bethe vectors.

A universality test of the quantum string Bethe ansatz [PDF]

open access: yes, 2006
We show that the quantum corrected string Bethe ansatz passes an important universality test by demonstrating that it correctly incorporates the non-analytical terms in the string sigma model one-loop correction for rational three-spin strings with two ...

Integrable Boundary Flows and the g-function [PDF]

open access: yes, 2012
This thesis explores renormalisation group flows in integrable quantum field theories with boundaries, as described by the g-function. The main focus is on the g-function in the staircase model, the renormalisation group flow of which passes close to the
