Gauss Coordinates vs Currents for the Yangian Doubles of the Classical Types

Andrii Liashyk, Stanislav Z. Pakuliak

We consider relations between Gauss coordinates of $T$ -operators for the Yangian doubles of the classical types corresponding to the algebras $g$ of $A$ , $B$ , $C$ and $D…

New approach to scalar products of Bethe vectors

A. Liashyk

We consider quantum integrable models solvable by the algebraic Bethe ansatz and possessing $gl (2)$ -invariant $R$ -matrix. We study the models of both periodic boundary c…
