Black holes: complementarity or firewalls?
- Ahmed Almheiri, D. Marolf, J. Polchinski, J. Sully
- Physics
- 13 July 2012
A bstractWe argue that the following three statements cannot all be true: (i) Hawking radiation is in a pure state, (ii) the information carried by the radiation is emitted from the region near the… Expand
Quantization of diffeomorphism invariant theories of connections with local degrees of freedom
- A. Ashtekar, J. Lewandowski, D. Marolf, J. Mourao, T. Thiemann
- Mathematics, Physics
- 12 April 1995
Quantization of diffeomorphism invariant theories of connections is studied and the quantum diffeomorphism constraint is solved. The space of solutions is equipped with an inner product that is shown… Expand
An apologia for firewalls
- Ahmed Almheiri, D. Marolf, J. Polchinski, D. Stanford, James Sully
- Physics
- 24 April 2013
A bstractWe address claimed alternatives to the black hole firewall. We show that embedding the interior Hilbert space of an old black hole into the Hilbert space of the early radiation is… Expand
The entropy of bulk quantum fields and the entanglement wedge of an evaporating black hole
- Ahmed Almheiri, N. Engelhardt, D. Marolf, H. Maxfield
- Physics
- 21 May 2019
Bulk quantum fields are often said to contribute to the generalized entropy $\frac{A}{4G_N} +S_{\mathrm{bulk}}$ only at $O(1)$. Nonetheless, in the context of evaporating black holes, $O(1/G_N)$… Expand
Setting the boundary free in AdS/CFT
- G. Compère, D. Marolf
- Physics
- 13 May 2008
We describe a new class of boundary conditions for AdSd+1 under which the boundary metric becomes a dynamical field. The key technical point is to show that contributions from boundary counter-terms… Expand
Holographic renormalization of asymptotically flat spacetimes
A new local, covariant 'counter-term' is used to construct a variational principle for asymptotically flat spacetimes in any spacetime dimension d ≥ 4. The new counter-term makes direct contact with… Expand
Proof of classical versions of the Bousso entropy bound and of the generalized second law
- E. Flanagan, D. Marolf, R. Wald
- Physics
- 9 August 1999
Bousso has conjectured that in any spacetime satisfying Einstein's equation and satisfying the dominant energy condition, the "entropy flux" S through any null hypersurface L generated by geodesics… Expand
On the Nonlinear Stability of Asymptotically Anti-de Sitter Solutions
- Ó. J. Dias, G. Horowitz, D. Marolf, J. E. Santos
- Physics
- 28 August 2012
Despite the recent evidence that anti-de Sitter (AdS) spacetime is nonlinearly unstable, we argue that many asymptotically AdS solutions are nonlinearly stable. This includes geons, boson stars and… Expand
On the support of the Ashtekar-Lewandowski measure
AbstractWe show that the Ashtekar-Isham extension
$$\overline {A/G}$$
of the configuration space of Yang-Mills theories
$$A/G$$
is (topologically and measure-theoretically) the projective limit of… Expand
Boundary Conditions and New Dualities : Vector Fields in AdS / CFT
In AdS, scalar fields with masses slightly above the Breitenlohner-Freedman bound admit a variety of possible boundary conditions which are reflected in the Lagrangian of the dual field theory.… Expand
