A positive energy theorem for asymptotically de Sitter spacetimes
DE sitter spacetime conserved DE sitter universe spinor and energy
2014/12/22
We construct a set of conserved charges for asymptotically de Sitter spacetimes that correspond to asymptotic conformal isometries. The charges are given by boundary integrals at spatial infinity in t...
Hadamard States for the Vector Potential on Asymptotically Flat Spacetimes
Hadamard States Asymptotically Flat Spacetimes General Relativity and Quantum Cosmology
2011/7/28
Abstract: We develop a quantization scheme for the vector potential on globally hyperbolic spacetimes which realizes it as a locally covariant conformal quantum field theory. This result allows us to ...
There has been significant interest in the last several years in studying possible gravitational duals, known as Lifshitz spacetimes, to anisotropically scaling field theories by adding matter to dis...
Holography and colliding gravitational shock waves in asymptotically AdS_5 spacetime
Holography colliding gravitational shock waves
2010/12/23
Using holography, we study the collision of planar shock waves in strongly coupled N=4 supersymmetric Yang-Mills theory. This requires the numerical solution of a dual gravitational initial value prob...
The Boundary Multiplet of N=4 SU(2)xU(1) Gauged Supergravity on Asymptotically-AdS_5
The Boundary Multiplet Gauged Supergravity
2010/12/23
We consider N=4 SU(2)xU(1) gauged supergravity on asymptotically-AdS_5 backgrounds. By a near-boundary analysis we determine the boundary-dominant components of the bulk fields from their partially g...
Entropy Production during Asymptotically Safe Inflation
Entropy Production Asymptotically Safe Inflation
2010/12/23
The Asymptotic Safety scenario predicts that the deep ultraviolet of Quantum Einstein Gravity is governed by a nontrivial renormalization group fixed point. Analyzing its implications for cosmology us...

Asymptotically flat stable black hole solutions
2010/12/23
We construct finite mass, asymptotically flat black hole solutions in d=5 Einstein--Yang-Mills--Chern-Simons theory. Our results indicate the existence of a second order phase transition between Reiss...

2010/12/21
We construct finite mass, asymptotically flat black hole solutions in d = 5 Einstein–Yang-Mills–Chern-Simons theory. Our results indicate the existence of a second order phase transition between Reiss...
Cosmology of an asymptotically free scalar field with spontaneous symmetry breaking
asymptotically free scalar spontaneous symmetry breaking
2010/12/20
We solve Einstein’s equation with Robertson-Walker metric as an initial-value problem, using as the source of gravity a Halpern-Huang real scalar field, which was derived from renormalization-group an...
A family of asymptotically good quantum codes based on code concatenation
A family of asymptotically good quantum codes code concatenation
2010/4/7
We explicitly construct an infinite family of asymptotically good concatenated quantum stabilizer codes where the outer code uses CSS-type quantum Reed-Solomon code and the inner code uses a set of sp...
Peeling properties of asymptotically flat solutions to the Einstein vacuum equations
asymptotically flat Einstein vacuum equations
2014/4/3
One of the central difficulties in connection to the L^2 bounded curvature conjecture in general relativity is to be able to control the causal structure of spacetimes with this very limited regularit...
