Holographic Ricci dark energy in Randall-Sundrum braneworld: Avoidance of big rip and steady state future
Chao-Jun Feng, Xin Zhang
In the holographic Ricci dark energy (RDE) model, the parameter plays an important role in determining the evolutionary behavior of the dark energy. When , the RDE will…
Chaplygin inflation in loop quantum cosmology
Xin Zhang, Jingfei Zhang, Jinglei Cui +1
In this paper we discuss the inflationary universe in the context of a Chaplygin gas equation of state within the framework of the effective theory of loop quantum cosmology. Under…
Exotic Statistics for Ordinary Particles in Quantum Gravity
John Swain
Objects exhibiting statistics other than the familiar Bose and Fermi ones are natural in theories with topologically nontrivial objects including geons, strings, and black holes. I…
Can black holes be torn up by phantom dark energy in cyclic cosmology?
Xin Zhang
Infinitely cyclic cosmology is often frustrated by the black hole problem. It has been speculated that this obstacle in cyclic cosmology can be removed by taking into account a pec…
