Integrability and RG flow in 2d sigma models

Nat Levine

Motivated by the search for solvable string theories, we consider the problem of classifying the integrable bosonic 2d $σ$ -models. We include non-conformal $σ$ -models, which have h…

Integrability vs. RG flow in $G \times G$ and $G \times G / H$ sigma models

Nat Levine, Arkady A. Tseytlin

We consider a class of 2d $σ$ -models on products of group spaces that provide new examples of a close connection between integrability and stability under the RG flow. We first stu…
