Non-Abelian Thirring model at large
Songyuan Li, Konstantinos Siampos
We consider the non-Abelian bosonized Thirring model for a semi-simple group at level , with deformation parameter . We compute the two-point correlation functions of cu…
Scale without conformal invariance from integrable deformations of coset CFTs
Georgios Itsios, Konstantinos Siampos
We construct the -model on and we compute the one-loop -function for the deformation parameter . Its non-compact version for i…
On the geometric origin of the energy-momentum tensor improvement terms
Damianos Iosifidis, Manthos Karydas, Anastasios Petkou +1
In a flat background, the canonical energy momentum tensor of Lorentz and conformally invariant matter field theories can be improved to a symmetric and traceless tensor that gives…
Integrability of the -deformation of the PCM with spectators
Riccardo Borsato, Georgios Itsios, J. Luis Miramontes +1
We construct a generalisation of the -deformation of the Principal Chiral Model (PCM) where we deform just a subgroup of the full symmetry group . We find that demanding…
