Costa, I., Forini, V., Hoare, B., Meier, T., Patella, A., & Weber, J. H. (2022, August). Supersphere non-linear sigma model on the lattice. Presented at The 39th International Symposium on Lattice Field Theory, Bonn, Germany

Two-dimensional O(N) non-linear sigma models are exactly solvable theories and have many applications, from statistical mechanics to their use as QCD toy models. We consider a supersymmetric extension, the non-linear sigma model on the supersphere~SN... Read More about Supersphere non-linear sigma model on the lattice.

Integrable string sigma models on AdS3 backgrounds with 16 supersymmetries have the distinguishing feature that their superisometry group is a direct product. As a result the deformation theory of these models is particularly rich since the two super... Read More about Bi-η and bi-λ deformations of ℤ4 permutation supercosets.
