Decrypting the warped black strings

Abstract

We propose a map for extracting the holographic meaning of the metric for a class of warped AdS3 black strings in type IIB supergravity. Our choice of holographic data is based upon a general prescription due to Papadimitriou. With this choice, we find a holographic stress tensor that is both symmetric and conserved, at least when restricted to a particular sector of the theory. Using the holographic stress tensor, we compute the energy and momentum per unit length of the black strings, as well as the conformal anomaly, and we show that the results agree with those previously obtained via covariant methods.
