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 cur…
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 is a…
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…
Chern-Simons action and the Carrollian Cotton tensors
Olivera Miskovic, Rodrigo Olea, P. Marios Petropoulos +2
In three-dimensional pseudo-Riemannian manifolds, the Cotton tensor arises as the variation of the gravitational Chern-Simons action with respect to the metric. It is Weyl-covarian…
Supersymmetric backgrounds from -deformations
Georgios Itsios, Konstantinos Sfetsos, Konstantinos Siampos
We provide the first supersymmetric embedding of an integrable -deformation to type-II supergravity. Specifically, that of the near horizon of the NS1-NS5 brane intersection, ge…
