Abstract
We discuss a one-parameter family of composite fields which generalise the TTbar operator to arbitrary spacetime dimensions. We show that they induce a deformation of the classical action, which is dynamically equivalent to a field-dependent modification of the metric according to a specific flow equation. We consider a family of abelian gauge theories as particular examples in d = 4. For such models, we obtain the exact expression of the deformed metric. These results imply that the recently proposed Modified Maxwell (ModMax) theory in a specific curved space is dynamically equivalent to its Born-Infeld-like extension in flat spacetime. We also discuss a dimensional reduction of the latter systems from d=4 to d=2 in which an interesting marginal deformation (the so-called root-TTbar deformation) of d=2 field theories emerges.
