Cosmology in p-brane systems
Cosmology p-brane systems
2010/12/23
We present time dependent solutions in the higher-dimensional gravity which are related to supergravity in the particular cases. Here we consider p-branes with a cosmological constant and the interse...
It has been recently proposed that the interpretation of gravity as an emergent, entropic force might have nontrivial implications to cosmology. Here two approaches are investigated: in one, the Fried...
SO(10) SUSY GUTs with mainly axion cold dark matter: implications for cosmology and colliders
Supersymmetry Grand unified theories axions
2010/3/16
Supersymmetric grand unified theories based on the gauge group SO(10) are highly motivated. In the simplest models, one expects t-b-\tau Yukawa coupling unification, in addition to gauge, matter and H...
Dynamical Horizon Entropy Bound Conjecture in Loop Quantum Cosmology
entropy bound conjecture Loop Quantum Cosmology
2010/3/17
The covariant entropy bound conjecture is an important hint for the quantum gravity, with several versions available in the literature. For cosmology, Ashtekar and Wilson-Ewing ever show the consisten...
