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…

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…

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…
