Heat as an inertial force: A quantum equivalence principle
K. Thanjavur, W. Israel
The firewall was introduced into black hole evaporation scenarios as a deus ex machina designed to break entanglements and preserve unitarity (Almheiri et.al., 2013). Here we show…
Shenanigans at the black hole horizon: pair creation or Boulware accretion?
Werner Israel
The current scenario of black hole evaporation holds that the Hawking energy flux is powered by pair creation at the horizon. However, pair creation produces entanglements, som…
A Massless Firewall
Werner Israel
Several anomalies of black hole thermodynamics are resolved if one accepts hints from semi classical theory that in regions of strong gravity the energy density of the vacuum can b…
Dark energy, wormholes, and the Big Rip
Valerio Faraoni, Werner Israel
The time evolution of a wormhole in a Friedmann universe approaching the Big Rip is studied. The wormhole is modeled by a thin spherical shell accreting the superquintessence fluid…
Lagrangian Brane Dynamics in General Relativity and Einstein-Gauss-Bonnet Gravity
Claude Barrabes, Werner Israel
This paper gives a new, simple and concise derivation of brane actions and brane dynamics in general relativity and in Einstein-Gauss-Bonnet gravity. We present a unified treatment…
The Aichelburg-Sexl Boost of Domain-Walls and Cosmic Strings
C. Barrabes, P. A. Hogan, W. Israel
We consider the application of the Aichelburg-Sexl boost to plane and line distributions of matter. Our analysis shows that for a domain wall the space-time after the boost is flat…
Moving-mirror entropy
Shinji Mukohyama, Werner Israel
We consider a quantized scalar field in a two-dimensional Minkowski spacetime with a moving mirror and propose a definition of moving-mirror entropy associated with temporarily ina…
Quantum Flux from a Moving Spherical Mirror
Warren G. Anderson, Werner Israel
We calculate the flux from a spherical mirror which is expanding or contracting with nearly uniform acceleration. We find that the flux at an exterior point (which could in princip…
Black holes, brick walls and the Boulware state
Shinji Mukohyama, Werner Israel
The brick-wall model seeks to explain the Bekenstein-Hawking entropy as a wall-contribution to the thermal energy of ambient quantum fields raised to the Hawking temperature. Reser…
Quasi-Spherical Light Cones of the Kerr Geometry
Frans Pretorius, Werner Israel
Quasi-spherical light cones are lightlike hypersurfaces of the Kerr geometry that are asymptotic to Minkowski light cones at infinity. We develop the equations of these surfaces an…
An Operational Approach To Black Hole Entropy
F. Pretorius, D. Vollick, W. Israel
In this paper we calculate the entropy of a thin spherical shell that contracts reversibly from infinity down to its event horizon. We find that, for a broad class of equations of…
Orbits, forces and accretion dynamics near spinning black holes
C. Barrabes, B. Boisseau, W. Israel
We analyze the relativistic dynamical properties of Keplerian and non-Keplerian circular orbits in a general axisymmetric and stationary gravitational field, and discuss the implic…
Structure of the Spherical Black Hole Interior
A. Bonanno, S. Droz, W. Israel +1
The internal structure of a charged spherical black hole is still a topic of debate. In a nonrotating but aspherical gravitational collapse to form a spherical charged black hole,…
