Observables in effective gravity
Steven B. Giddings, Donald Marolf, James B. Hartle
We address the construction and interpretation of diffeomorphism-invariant observables in a low-energy effective theory of quantum gravity. The observables we consider are construc…
Lodged in the throat: Internal infinities and AdS/CFT
Don Marolf, Amos Yarom
In the context of AdS3/CFT2, we address spacetimes with a certain sort of internal infinity as typified by the extreme BTZ black hole. The internal infinity is a null circle lying…
A black hole instability in five dimensions?
Donald Marolf, Amitabh Virmani
We study the moduli-space scattering of a two-charge supertube in the background of a rotating BPS D1-D5-P black hole in 4+1 dimensions, extending the static analysis of Bena and K…
On the fate of black string instabilities: An Observation
Donald Marolf
Gregory and Laflamme (hep-th/9301052) have argued that an instability causes the Schwarzschild black string to break up into disjoint black holes. On the other hand, Horowitz and M…
Comparison between various notions of conserved charges in asymptotically AdS-spacetimes
S. Hollands, A. Ishibashi, D. Marolf
We derive hamiltionian generators of asymptotic symmetries for general relativity with asymptotic AdS boundary conditions using the ``covariant phase space'' method of Wald et al.…
Black hole entropy: inside or out?
Ted Jacobson, Donald Marolf, Carlo Rovelli
A trialogue. Ted, Don, and Carlo consider the nature of black hole entropy. Ted and Carlo support the idea that this entropy measures in some sense ``the number of black hole micro…
