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

The entropy of bulk quantum fields and the entanglement wedge of an evaporating black hole

Abstract
Bulk quantum fields are often said to contribute to the generalized entropy

An apologia for firewalls

- Ahmed Almheiri, D. Marolf, J. Polchinski, D. Stanford, J. Sully
- Mathematics
- 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

Quantization of diffeomorphism invariant theories of connections with local degrees of freedom

- A. Ashtekar, J. Lewandowski, D. Marolf, J. Mourao, T. Thiemann
- Mathematics
- 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

Transcending the ensemble: baby universes, spacetime wormholes, and the order and disorder of black hole information

- D. Marolf, Henry Maxfield
- Physics
- 20 February 2020

In the 1980's, work by Coleman and by Giddings and Strominger linked the physics of spacetime wormholes to `baby universes' and an ensemble of theories. We revisit such ideas, using features… 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

Proof of classical versions of the Bousso entropy bound and of the generalized second law

- E. Flanagan, D. Marolf, R. Wald
- Mathematics
- 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

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

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

On the Nonlinear Stability of Asymptotically Anti-de Sitter Solutions

- Ó. J. Dias, G. Horowitz, D. Marolf, Jorge 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
