What is the gravity dual of a chiral primary?
Oleg Lunin, Samir D. Mathur, Ashish Saxena
In the AdS/CFT correspondence a chiral primary is described by a supergravity solution with mass equaling angular momentum. For AdS_3 X S^3 we are led to consider three special fam…
Brane World Gravity in an AdS Black Hole
Richard C. Brower, Samir D. Mathur, Chung-I Tan
We consider a model of brane world gravity in the context of non-conformal non-SUSY matter. In particular we modify the earlier strong coupling solution to the glueball spectrum in…
Rotating deformations of AdS_3\times S^3, the orbifold CFT and strings in the pp-wave limit
Oleg Lunin, Samir D. Mathur
We construct an exact metric which at short distances is the metric of massless particles in 5+1 spacetime (moving along a diameter of the sphere) and is AdS_3\times S^3 at infinit…
A proposal to resolve the black hole information paradox
Samir D. Mathur
The entropy and information puzzles arising from black holes cannot be resolved if quantum gravity effects remain confined to a microscopic scale. We use concrete computations in n…
Scalar propagator in the pp-wave geometry obtained from AdS_5 X S^5
Samir D. Mathur, Ashish Saxena, Yogesh K. Srivastava
We compute the propagator for massless and massive scalar fields in the metric of the pp-wave. The retarded propagator for the massless field is found to stay confined to the surfa…
Statistical interpretation of Bekenstein entropy for systems with a stretched horizon
Oleg Lunin, Samir D. Mathur
For the 2-charge extremal holes in string theory we show that the Bekenstein entropy obtained from the area of the stretched horizon has a statistical interpretation as a `coarse g…
