Bethe Ansatz without Nesting

Gleb Arutyunov, Hrachya Babujian, Minghao Gao

We develop a non-nested Bethe ansatz description of rational $gl_{ℓ}$ spin chains in the vector representation. Starting from the quantum spectral curve and the separat…

Nonequilibrium from Equilibrium: Chiral Current-Carrying States in the Spin-1 Babujian-Takhtajan Chain

Bahar Jafari-Zadeh, Chenan Wei, Hrachya M. Babujian +1

We study the spin- $1$ Babujian-Takhtajan chain deformed by its third conserved charge $Q_{3}$ . We derive $Q_{3}$ and show that it is a dimensionless energy current and that its local d…

Structure Functions for small DIS $x$

Hrachya M. Babujian, Angela Foerster, Michael Karowski

Structure Functions for small DIS (deep inelastic scattering) $x$ for integrable models are investigated, in particular, for the $O (N)$ ~ $I ¨ $ -model and $S U (N)$ chiral Gross-Neveu mo…

Factorization in deep inelastic scattering at BjÃ¶rken limit: Reduction to (1+1)D integrable models

H. Babujian, M. Karowski, A. Sedrakyan

We investigate structure functions in deep inelastic scattering processes (DIS) at BjÃ¶rken limit and found that they are factorized into the longitudinal and transversal parts. We…
