Spinning strings: $\lambda$-deformation and non-Abelian T-dual limit

Rafael Hernandez, Roberto Ruiz, Konstantinos Sfetsos

The simplest example of the $\lambda$-deformation connects the SU(2) Wess-Zumino-Witten model with the non-Abelian T-dual (NATD) of the SU(2) principal chiral model. We analyze spinning…
