On generalized Q-systems

open access: yesJournal of High Energy Physics, 2020
We formulate Q-systems for the closed XXZ, open XXX and open quantum- group-invariant XXZ quantum spin chains. Polynomial solutions of these Q-systems can be found efficiently, which in turn lead directly to the admissible solutions of the corresponding ...

Equilibrium dynamical correlations in the Toda chain and other integrable models. [PDF]

open access: yesPhysical Review E, 2016
We investigate the form of equilibrium spatiotemporal correlation functions of conserved quantities in the Toda lattice and in other integrable models. From numerical simulations we find that the correlations satisfy ballistic scaling with a remarkable ...

On a method for constructing the Lax pairs for integrable models via a quadratic ansatz [PDF]

open access: yes, 2017
A method for constructing the Lax pairs for nonlinear integrable models is suggested. First we look for a nonlinear invariant manifold of the linearization of the given equation.

Nonsymmetric Macdonald polynomials via integrable vertex models [PDF]

open access: yesTransactions of the American Mathematical Society, 2019
Starting from an integrable rank-$n$ vertex model, we construct an explicit family of partition functions indexed by compositions $\mu = (\mu_1,\dots,\mu_n)$.

New compact construction of eigenstates for supersymmetric spin chains

open access: yesJournal of High Energy Physics, 2018
The problem of separation of variables (SoV) in supersymmetric spin chains is closely related to the calculation of correlation functions in N=4 $$ \mathcal{N}=4 $$ SYM theory which is integrable in the planar limit.

A novel class of translationally invariant spin chains with long-range interactions

open access: yesJournal of High Energy Physics, 2020
We introduce a new class of open, translationally invariant spin chains with long-range interactions depending on both spin permutation and (polarized) spin reversal operators, which includes the Haldane-Shastry chain as a particular degenerate case. The

New integrable 1D models of superconductivity [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2019
In this paper we find new integrable one-dimensional lattice models of electrons. We describe all such nearest-neighbour integrable models with su(2)×su(2) symmetry by classifying solutions of the Yang–Baxter equation following the procedure first ...

On a systematic approach to defects in classical integrable field theories [PDF]

open access: yes, 2008
We present an inverse scattering approach to defects in classical integrable field theories. Integrability is proved systematically by constructing the generating function of the infinite set of modified integrals of motion.

On zero-remainder conditions in the Bethe ansatz

open access: yesJournal of High Energy Physics, 2020
We prove that physical solutions to the Heisenberg spin chain Bethe ansatz equations are exactly obtained by imposing two zero-remainder conditions. This bridges the gap between different criteria, yielding an alternative proof of a recently devised ...
