TT deformations in general dimensions
TT deformations in general dimensions
It has recently been proposed that Zamoldchikov’s TT deformationof two-dimensional CFTs describes the holographic theory dual toAdS3 at finite radius. In this note we use the Gauss-Codazzi formof the Einstein equations to derive a relationship in general dimensions between the trace of the quasi-local stress tensor and a specific quadratic combination of this stress tensor, on constant radius slices of AdS. We use this relation to propose a generalization of Zamoldchikov’s TT deformation to conformal field theories in general dimensions. This operator is quadratic in the stress tensor and retains many but not all of the features of TT. To describe gravity with gauge or scalar fields, the deforming operator needs to be modified to include appropriate terms involving the corresponding R currents and scalar operators and we can again use the Gauss-Codazzi form of the Einstein equations to deduce the forms of the deforming operators. We conclude by discussing the relation of the quadratic stress tensor deformation to the stress energy tensor trace constraint in holographic theories dual to vacuum Einstein gravity.

Abstract
It has recently been proposed that Zamoldchikov’s TT deformationof two-dimensional CFTs describes the holographic theory dual toAdS3 at finite radius. In this note we use the Gauss-Codazzi formof the Einstein equations to derive a relationship in general dimensions between the trace of the quasi-local stress tensor and a specific quadratic combination of this stress tensor, on constant radius slices of AdS. We use this relation to propose a generalization of Zamoldchikov’s TT deformation to conformal field theories in general dimensions. This operator is quadratic in the stress tensor and retains many but not all of the features of TT. To describe gravity with gauge or scalar fields, the deforming operator needs to be modified to include appropriate terms involving the corresponding R currents and scalar operators and we can again use the Gauss-Codazzi form of the Einstein equations to deduce the forms of the deforming operators. We conclude by discussing the relation of the quadratic stress tensor deformation to the stress energy tensor trace constraint in holographic theories dual to vacuum Einstein gravity.
