Description
The QQ-system plays a crucial role in the study of many integrable models, and it is the cornerstone of many techniques such as the Quantum Spectral Curve and the Separation of Variables. We will explore the structure of the QQ-system for the osp(4|2) super Lie algebra. Its key application will be the Quantum Spectral Curve for the study of string theory on AdS₃ × S³ × S³ × S¹ background with pure RR fluxes, which exhibits osp(4|2) x osp(4|2) symmetry when the radii of the two S³ factors are equal. From a comparison with the Asymptotic Bethe Ansatz and some inspiration from previous works, I will discuss a proposal for the analytical properties of the Q-functions in the osp(4|2) x osp(4|2) QQ-system that can be used to study this theory.
