Bi- $η$ and bi- $λ$ deformations of $Z_{4}$ permutation supercosets

Ben Hoare, Nat Levine, Fiona K. Seibold

Integrable string sigma models on AdS $_{3}$ backgrounds with 16 supersymmetries have the distinguishing feature that their superisometry group is a direct product. As a result the de…

Universal 1-loop divergences for integrable sigma models

Nat Levine

We present a simple, new method for the 1-loop renormalization of integrable $σ$ -models. By treating equations of motion and Bianchi identities on an equal footing, we derive 'univ…
