Deriving the $AdS_{3} \times S^{3} \times T^{4}$ Quantum Spectral Curve I: Y-system and discontinuity relations

Andrea CavagliÃ, NicolÃ² Primi, Davide Polvara +2

The paper derives the Y-system and its discontinuity relations for the pure‑Ramond‑Ramond AdS₃×S³×T⁴ superstring from the mirror Thermodynamic Bethe Ansatz, laying groundwork for a…

Perturbed symmetric-product orbifold: first-order mixing and puzzles for integrability

Matheus Fabri, Alessandro Sfondrini, Torben Skrzypek

We study the marginal deformation of the symmetric-product orbifold theory Sym $_{N} (T^{4})$ which corresponds to introducing a small amount of Ramond-Ramond flux into the dual $AdS_3\t…

Exchange relations and crossing

Sergey Frolov, Davide Polvara, Alessandro Sfondrini

We discuss the scattering matrix of two-dimensional integrable QFTs whose fields obey non-trivial exchange relations. We show that crossing equations for such models have to be mod…

Interpolating families of integrable AdS3 backgrounds

Fiona K. Seibold, Alessandro Sfondrini

We construct families of integrable deformations that interpolate between $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$ and either $A d S_{3} \times S^{3} \times S^{2} \times T^{2}$ or $AdS_3\times S^2…
