RG flows of integrable -models and the twist function
François Delduc, Sylvain Lacroix, Konstantinos Sfetsos +1
In the study of integrable non-linear -models which are assemblies and/or deformations of principal chiral models and/or WZW models, a rational function called the twist functio…
Asymmetric CFTs arising at the IR fixed points of RG flows
George Georgiou, Georgios P. D. Pappas, Konstantinos Sfetsos
We construct a generalization of the cyclic -deformed models of \cite{Georgiou:2017oly} by relaxing the requirement that all the WZW models should have the same level . Our t…
A free field perspective of -deformed coset CFT's
George Georgiou, Konstantinos Sfetsos, Konstantinos Siampos
We continue our study of -deformed -models by setting up a perturbative expansion around the free field point for cosets, in particular for the -deformed $SU(2)/U(1)…
