What is an integrable quench?

Nuclear Physics B, 2017
Inspired by classical results in integrable boundary quantum field theory, we propose a definition of integrable initial states for quantum quenches in lattice models.

Exact finite volume expectation values of Ψ ¯ Ψ $$ \overline{\varPsi}\varPsi $$ in the massive Thirring model from light-cone lattice correlators

Journal of High Energy Physics, 2018
In this paper, using the light-cone lattice regularization, we compute the finite volume expectation values of the composite operator Ψ ¯ Ψ $$ \overline{\varPsi}\varPsi $$ between pure fermion states in the Massive Thirring Model.

Boundary overlaps from Functional Separation of Variables

Journal of High Energy Physics
In this paper we show how the Functional Separation of Variables (FSoV) method can be applied to the problem of computing overlaps with integrable boundary states in integrable systems.

Lattice approach to finite volume form-factors of the Massive Thirring (Sine-Gordon) model

Journal of High Energy Physics, 2017
In this paper we demonstrate, that the light-cone lattice approach for the Massive-Thirring (sine-Gordon) model, through the quantum inverse scattering method, admits an appropriate framework for computing the finite volume form-factors of local ...

Lattice Analogues of $N=2$ Superconformal Models via Quantum Group Truncation

, 1992
We obtain lattice models whose continuum limits correspond to $N=2$ superconformal coset models. This is done by taking the well known vertex model whose continuum limit is the $G \times G/G$ conformal field theory, and twisting the transfer matrix and ...

Off-diagonal Bethe Ansatz for the D 3 1 $$ {D}_3^{(1)} $$ model

Journal of High Energy Physics, 2019
The exact solutions of the D 3 1 $$ {D}_3^{(1)} $$ model (or the so(6) quantum spin chain) with either periodic or general integrable open boundary conditions are obtained by using the off-diagonal Bethe Ansatz.

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.

Multicolored Temperley-Lieb lattice models. The ground state

, 2006
Using inversion relation, we calculate the ground state energy for the lattice integrable models, based on a recently obtained baxterization of non trivial multicolored generalization of Temperley-Lieb algebras.

Integrable lattice models and supersymmetry

, 2020
One of the goals of statistical physics is to understand the magnetic properties of the matter from the atomic properties and interactions. In this dissertation, we study the famous XXZ and XYZ spin-chains, which are one-dimensional spin-1/2 models.

The 4-CB algebra and solvable lattice models

Journal of High Energy Physics, 2019
We study the algebras underlying solvable lattice models of the type fusion interaction round the face (IRF). We propose that the algebras are universal, depending only on the number of blocks, which is the degree of polynomial equation obeyed by the ...
