Abstract

We explore TTbar deformations of Warped Conformal Field Theories (WCFTs) as examples of TTbar deformed non-relativistic quantum field theories. We first look at deformations of free-field realizations of WCFTs, i.e. the Hofman-Rollier fermionic WCFTs, which lose their warped conformal symmetry when deformed. We then compute the deformed symmetry algebra of a TTbar deformed holographic WCFT, using the asymptotic symmetries of AdS3 with a set of TTbar deformed boundary conditions. We see that the U(1) Kac-Moody symmetry does not survive the deformation. The Virasoro sector remains but is now deformed and no longer chiral.
