Solvable K-essence Cosmologies and Modified Chaplygin Gas Unified Models of Dark Energy and Dark Matter
Solvable K-essence Cosmologies Modified Chaplygin Gas Unified Models of Dark Energy Dark Matter
2012/4/20
This paper is devoted to the investigation of modified Chaplygin gas model in the context of solvable k-essence cosmologies. For this purpose, we construct equations of state parameter of this model f...
Notes on dark energy interacting with dark matter and unparticle in loop quantum cosmology
Notes dark energy dark matter unparticle loop quantum cosmology
2011/8/3
Abstract: We investigate the behavior of dark energy interacting with dark matter and unparticle in the framework of loop quantum cosmology. In four toy models, we study the interaction between the co...
Dark Matter as a Relativistic Inertial Effect in Einstein Canonical Gravity?
Dark Matter Relativistic Inertial Effect Einstein Canonical Gravity
2010/12/20
After the study of non-inertial frames in special relativity with emphasis on the problem of clock synchronization (i.e. of how to define 3-space), an overview is given of Einstein canonical gravity i...
Unified Dark Matter scalar field models with fast transition
Unified Dark Matter scalar field fast transition

We investigate the general properties of Unified Dark Matter (UDM) scalar
field models with Lagrangians with a non-canonical kinetic term, looking specifically for
models that can produce a fast tra...

Experimental studies of gravity Dark matter Solar system objects Celestial mechanics
2010/3/17
We apply our recent results on orbital dynamics around a mass-varying central body to the phenomenon of accretion of Dark Matter-assumed not self-annihilating-on the Sun and the major bodies of the so...
For particle physicists analysing the first data from CERN’s Large Hadron Collider (LHC) in Geneva, it is the �4.3 bn question: is there a particle known as the Higgs, which endows all others with mas...
