Title: Baxter Q-operators for rational spin chains

Rouven Frassek (IHES, Paris)

 

Abstract:

After giving a short review of the quantum inverse scattering method I will discuss how Q-operators can be constructed in this framework. The approach employs an infinite dimensional auxiliary space and follows the ideas of Bazhanov, Lukyanov and Zamolodchikov. The R-matrices relevant belong to a set of degenerate solutions to the Yang-Baxter equation. The construction is exemplified for the closed and open Heisenberg chain but also for non-compact spin chains, which are relevant for high energy QCD and N=4 super Yang-Mills theory. Finally, I discuss the generalisation of the construction to higher rank Lie algebras.
