AdS$_3$ and AdS$_2$ Magnetic Brane Solutions
Magnetic Brane Solutions High Energy Physics
font style='font-size:12px;'>
2010/12/23
We investigate AdS$_3$ and AdS$_2$ magnetic brane solutions within the consistent truncation of AdS$_5 \times S^5$ supergravity. The AdS$_3$ solution extends earlier work by allowing a general embeddi...

A key question in the study of N=2 supersymmetric string or field theories is to understand the decay of BPS bound states across walls of marginal stability in the space of parameters or vacua. By re...
Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
Cosmic Microwave Background Radiation detecting cosmic strings
font style='font-size:12px;'>
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...

2010/12/23
We construct four-dimensional covariant non-linear theories of massive gravity which are ghost-free in the decoupling limit to all orders. These theories resum explicitly all the nonlinear terms of a...
Thermodynamics of third order Lovelock anti-de Sitter black holes revisited
Thermodynamics third order Lovelock anti-de Sitter black holes
font style='font-size:12px;'>
2010/12/27
We compute the mass and the temperature of third order Lovelock black holes with negative Gauss-Bonnet coefficient $\alpha_2<0$ in anti-de Sitter space and perform the stability analysis of topologica...
Holographic Q-Picture of Black Holes in Five Dimensional Minimal Supergravity
Holographic Q-Picture Black Holes Five Dimensional Minimal Supergravity
font style='font-size:12px;'>
2010/12/24
In this article, we explore the holographic Q-picture description for the charged rotating black holes in the five-dimensional minimal supergravity. The central charge in the Q-picture depends only o...
An old Einstein - Eddington generalized gravity and modern ideas on branes and cosmology
Einstein - Eddington generalized gravity branes cosmology
font style='font-size:12px;'>
2010/12/27
We briefly discuss new models of an `affine' theory of gravity in multidimensional space-times with symmetric connections. We use and generalize Einstein's proposal to specify the space-time geometry...
Ultraspinning instability of anti-de Sitter black holes
Ultraspinning instability anti-de Sitter
font style='font-size:12px;'>
2010/12/23
Myers-Perry black holes with a single spin in d>5 have been shown to be unstable if rotating sufficiently rapidly. We extend the numerical analysis which allowed for that result to the asymptotically ...
The $\cal{P}$-Parity Odd Universe, Dark Energy and QCD
Odd Universe Dark Energy QCD
font style='font-size:12px;'>
2010/12/27
Cosmological observations on the largest scales exhibit a solid record of unexpected anomalies and alignments, apparently pointing towards a large scale violation of statistical isotropy. These inclu...
Goldstone's Theorem and Hamiltonian of Multi-galileon Modified Gravity
Goldstone's Theorem Hamiltonian Multi-galileon Modified Gravity
font style='font-size:12px;'>
2010/12/23
The galileon model was recently proposed to locally describe a class of modified gravity theories, including the braneworld DGP model. We discuss spontaneous symmetry breaking of the self-accelerating...

2010/12/24
Concurrence is an entanglement measure characterizing the {\it mixed} state bipartite correlations inside of a pure state of an $n$-qubit system. We show that after organizing the charges and the mod...
The curvaton scenario in Brane cosmology: model parameters and their constraints
The curvaton scenario Brane cosmology model parameters
font style='font-size:12px;'>
2010/12/23
We have studied the curvaton scenario in brane world cosmology in an intermediate inflationary scenario. This approach has allowed us to find some constraints on different parameters that appear in th...
The influence of inhomogeneities on the large-scale expansion of the universe
the large-scale expansion universe
font style='font-size:12px;'>
2010/12/27
The evolution of an inhomogeneous universe composed entirely of matter is followed from an early, nearly uniform state until the time when the inhomogeneities have begun to grow large. The particular...
Gravity as an Entropic Phenomenon
Gravity Entropic Phenomenon
font style='font-size:12px;'>
2010/12/24
The unification of gravity with the three other forces has been an important goal of physics for some time now, because a quantum theory of gravity is necessary to explain the universe at its earliest...
Nonrelativistic general covariant theory of gravity with a running constant $\lambda$
Nonrelativistic general covariant theory gravity running constant
font style='font-size:12px;'>
2010/12/23
In this paper, we investigate three important issues: ghost, stability and strong coupling, in the Horava-Melby-Thompson (HMT) setup of the Horava-Lifshitz (HL) theory with $\lambda \not= 1$. We firs...
