Integrable deformations of the flat space sigma model
Khalil Idiab
We explore a deformation of the flat space symmetric space sigma model action. The deformed action is designed to allow a Lax connection for the equations of motion, similar to the…

On exactly solvable Yang-Baxter models and enhanced symmetries
Khalil Idiab, Stijn J. van Tongeren
We study Yang-Baxter deformations of the flat space string that result in exactly solvable models, finding the Nappi-Witten model and its higher dimensional generalizations. We the…
