Hypothetical particles called axions could solve two enigmas at once. They could account for dark matter, the mysterious substance that is thought to make up most of the matter in the Universe, and th...

In her most recent book, physicist Lisa Randall--Harvard professor, libretto composer, Lego figurine, star in the world of theoretical physics--writes that the universe repeatedly reveals itself ...
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...
Is dark matter an illusion created by the gravitational polarization of the quantum vacuum?
dark matter the quantum vacuum the gravitational polarization
2011/8/29
Assuming that a particle and its antiparticle have the gravitational charge of the opposite sign, the physical vacuum may be considered as a fluid of virtual gravitational dipoles. Following this hypo...
The field of dark matter direct detection has seen important contributions in recent years from experiments involving liquid noble gases, specifically liquid argon and liquid xenon. These detection me...

Cladogenesis: Baryon-Dark Matter Coincidence from Branchings in Moduli Decay
Cladogenesis Baryon-Dark Matter Coincidence
2010/12/24
We propose late-time moduli decay as the common origin of baryons and dark matter. The baryon asymmetry is produced from the decay of new TeV scale particles, while dark matter is created from the (c...
Low Mass Gluino within the Sparticle Landscape, Implications for Dark Matter, and Early Discovery Prospects at LHC-7
Low Mass Gluino Sparticle Landscape Dark Matter
2010/12/24
We analyze supergravity models that predict a low mass gluino within the landscape of sparticle mass hierarchies. The analysis includes a broad class of models that arise in minimal and in non-minimal...

Hierarchies of Susy Splittings and Invisible Photinos as Dark Matter
Susy Splittings Invisible Photinos Dark Matter
2010/12/24
We explore how to generate hierarchies in the splittings between superpartners. Some of the consequences are the existence of invisible components of dark matter, new inflaton candidates, invisible mo...
The Gauge-Invariant Bias of Dark Matter Haloes with Primordial non-Gaussianity
The Gauge-Invariant Dark Matter Haloes
2010/12/27
The non-linear evolution of the halo population is followed by solving the continuity equation under the hypothesis that haloes move by the action of gravity. An exact and general formula for the Eule...
