Randall-Sundrum limit of f(R) brane-world models
Randall-Sundrum limit brane-world models
2011/10/17
By setting some special boundary conditions in the variational principle we obtain junction conditions for the five-dimensional $f(R)$ gravity which in the Einstein limit $f(R)\rightarrow R$ transform...
In this paper we derive, directly from the Nambu-Goto action, the relevant components of the acceleration of cosmological featureless $p$-branes, extending previous analysis based on the field theory ...
Inflation with improved D3-brane potential and the fine tunings associated with the model
improved D3-brane potential the fine tunings associated
2011/1/13
We investigate brane-antibrane inflation in a warped deformed conifold background that includes contributions to the potential arising from imaginary anti-self-dual (IASD) fluxes including the term wi...
The curvaton scenario in Brane cosmology: model parameters and their constraints
Cosmology Intermediate Inflation Brane Curvaton
2010/11/16
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 t...
Spacetime Brout-Englert-Higgs effect in General Relativity interacting with p-brane matter
Brout-Englert-Higgs p-brane matter
2010/3/19
We review the manifestation of the Brout-Englert-Higgs effect in general relativity interacting with point-like and extended objects (p-branes including string for p=1 and membrane for p=2), which man...
It is widely recognized that the AdS/CFT correspondence is a useful tool to study strongly coupled field theories. On the other hand, Randall-Sundrum (RS) braneworld models have been actively discusse...
Need of Dark Energy for Dynamical Compactification of Extra Dimensions on the Brane
Dark Energy Dynamical Compactification the Brane
2010/10/18
We consider a six-dimensional braneworld model and we study the cosmological evolution of a (4+1) braneuniverse. Introducing matter on the brane we show that the scale factor of the physical three-dim...
