Baxter Q-operators in Ruijsenaars-Sutherland hyperbolic systems: one- and two-particle cases
N. Belousov, S. Derkachov, S. Kharchev +1
In these notes we review the technique of Baxter Q-operators in the Ruijsenaars-Sutherland hyperbolic systems in the cases of one and two particles. Using these operators we show i…

Baxter operators in Ruijsenaars hyperbolic system IV. Coupling constant reflection symmetry
N. Belousov, S. Derkachov, S. Kharchev +1
We introduce and study a new family of commuting Baxter operators in the Ruijsenaars hyperbolic system, different from that considered by us earlier. Using a degeneration of Rains…

Q-operator for the quantum NLS model
N. Belousov, S. Derkachov
In this paper we show that the operator introduced by A. A. Tsvetkov enjoys all the needed properties of a Q-operator. It is shown that the Q-operator of the XXX spin chain with ge…
