Alpha-Vacua, Black Holes, and AdS/CFT
Andrew Chamblin, Jeremy Michelson
The Schwarzschild, Schwarzschild-AdS, and Schwarzschild-de Sitter solutions all admit freely acting discrete involutions which commute with the continuous symmetries of the spaceti…
Hawking and Page on the brane
A. Chamblin, A. Karch
We show that the Hawking-Page phase transition of a CFT on AdS_{d-1} weakly coupled to gravity has a dual bulk description in terms of a phase transition between a black string and…
Twistors and Holography
Andrew Chamblin
We extend Bousso's notion of a lightsheet - a surface where entropy can be defined in a way so that the entropy bound is satisfied - to more general surfaces. Intuitively these sur…
Holographic Weyl Entropy Bounds
Andrew Chamblin, Joshua Erlich
We consider the entropy bounds recently conjectured by Fischler, Susskind and Bousso, and proven in certain cases by Flanagan, Marolf and Wald (FMW). One of the FMW derivations sup…
Zero-Branes, Quantum Mechanics and the Cosmological Constant
Andrew Chamblin, Neil D. Lambert
We analyse some dynamical issues in a modified type IIA supergravity, recently proposed as an extension of M-theory that admits de Sitter space. In particular we find that this the…
On the Eleven-Dimensional Origins of Polarized D0-branes
D. Brecher, A. Chamblin
The worldvolume theory of a D0-brane contains a multiplet of fermions which can couple to background spacetime fields. This coupling implies that a D0-brane may possess multipole m…
de Sitter space from M-theory?
Andrew Chamblin, Neil D. Lambert
In this note we study a massive IIA supergravity theory obtained in hep-th/9707139 by compactification of M-theory. We point out that de Sitter space in arbitrary dimensions arises…
A Bestiary of Higher Dimensional Taub-NUT-AdS Spacetimes
Adel Awad, Andrew Chamblin
We present a menagerie of solutions to the vacuum Einstein equations in six, eight and ten dimensions. These solutions describe spacetimes which are either locally asymptotically a…
AdS/CFT in the Infinite Momentum Frame
D. Brecher, A. Chamblin, H. S. Reall
This paper considers the spacetimes describing pp-waves propagating on extremal non-dilatonic branes. It is shown that an observer moving along a geodesic will experience infinite…
Capture of bulk geodesics by brane-world black holes
Andrew Chamblin
In this note we study bulk timelike geodesics in the presence of a brane-world black hole, where the brane-world is a two-brane moving in a 3+1-dimensional asymptotically s…
Charged Brane-World Black Holes
Andrew Chamblin, Harvey S. Reall, Hisa-aki Shinkai +1
We study charged brane-world black holes in the model of Randall and Sundrum in which our universe is viewed as a domain wall in asymptotically anti-de Sitter space. Such black hol…
Thermal Equilibration of Brane-Worlds
A. Chamblin, A. Karch, A. Nayeri
We analyze the thermodynamical properties of brane-worlds, with a focus on the second model of Randall and Sundrum. We point out that during an inflationary phase on the brane, bla…
Black Diamonds at Brane Junctions
Andrew Chamblin, Csaba Csaki, Joshua Erlich +1
We discuss the properties of black holes in brane-world scenarios where our universe is viewed as a four-dimensional sub-manifold of some higher-dimensional spacetime. We consider…
Puncture of gravitating domain walls
Andrew Chamblin, Douglas M. Eardley
We investigate the semi-classical instability of vacuum domain walls to processes where the domain walls decay by the formation of closed string loop boundaries on their worldvolum…
Branes, AdS gravitons and Virasoro symmetry
M. Banados, A. Chamblin, G. W. Gibbons
We consider travelling waves propagating on the anti-de Sitter (AdS) background. It is pointed out that for any dimension d, this space of solutions has a Virasoro symmetry with a…
Brane-World Black Holes
A. Chamblin, S. W. Hawking, H. S. Reall
Gravitational collapse of matter trapped on a brane will produce a black hole on the brane. We discuss such black holes in the models of Randall and Sundrum where our universe is v…
Supergravity on the Brane
A. Chamblin, G. W. Gibbons
We show that smooth domain wall spacetimes supported by a scalar field separating two anti-de-Sitter like regions admit a single graviton bound state. Our analysis yields a fully n…
Holography, Thermodynamics and Fluctuations of Charged AdS Black Holes
Andrew Chamblin, Roberto Emparan, Clifford V. Johnson +1
The physical properties of Reissner-Nordstrom black holes in (n+1)-dimensional anti-de Sitter spacetime are related, by a holographic map, to the physics of a class of n-dimensiona…
Charged AdS Black Holes and Catastrophic Holography
Andrew Chamblin, Roberto Emparan, Clifford V. Johnson +1
We compute the properties of a class of charged black holes in anti-de Sitter space-time, in diverse dimensions. These black holes are solutions of consistent Einstein-Maxwell trun…
Existence of Majorana fermions for M-branes wrapped in space and time
A. Chamblin
We show that it is possible to define Majorana (s)pinor fields on M-branes which have been identified under the action of the antipodal map on the adS factor of the throat geometry…
Large N Phases, Gravitational Instantons and the Nuts and Bolts of AdS Holography
Andrew Chamblin, Roberto Emparan, Clifford V. Johnson +1
Recent results in the literature concerning holography indicate that the thermodynamics of quantum gravity (at least with a negative cosmological constant) can be modeled by the la…
Superconducting p-branes and Extremal Black Holes
A. Chamblin, R. Emparan, G. W. Gibbons
In Einstein-Maxwell theory, magnetic flux lines are `expelled' from a black hole as extremality is approached, in the sense that the component of the field strength normal to the h…
Open inflation from non-singular instantons: Wrapping the universe with a membrane
Raphael Bousso, Andrew Chamblin
The four-form field recently considered by Hawking and Turok couples naturally to a charged membrane, across which the effective cosmological constant has a discontinuity. We prese…
Dynamic D8-branes in IIA string theory
A. Chamblin, M. J. Perry
In this paper we perform a detailed investigation of the Dirichlet eight-brane of the Type IIA string theory, when the effects of gravity are included. In particular, consider what…
