Q-Operators for Higher Spin Eight Vertex Models with an Even Number of Sites

Letters in Mathematical Physics. 2016. Vol. 106. No. 3. P. 319-340.

We construct the Q-operator for generalised eight vertex models associated to higher spin representations of the Sklyanin algebra, following Baxter's 1973 paper. As an application, we prove the sum rule for the Bethe roots.
