Baxter Q-Operators and Representations of Yangians

Bazhanov, Vladimir V.; Frassek, Rouven; Lukowski, Tomasz; Meneghelli, Carlo; Staudacher, Matthias

We develop a new approach to Baxter Q-operators by relating them to the theory of Yangians, which are the simplest examples for quantum groups. Here we open up a new chapter in this theory and study certain degenerate ...

Oscillator Construction of su(n|m) Q-Operators

Frassek, Rouven; Lukowski, Tomasz; Meneghelli, Carlo; Staudacher, Matthias

We generalize our recent explicit construction of the full hierarchy of Baxter Q-operators of compact spin chains with su(n) symmetry to the supersymmetric case su(n|m). The method is based on novel degenerate solutions ...
