Cosmological Constraints on the Sign-Changeable Interactions
Hao Wei
Recently, Cai and Su [Phys. Rev. D {\bf 81}, 103514 (2010)] found that the sign of interaction in the dark sector changed in the approximate redshift range of $0.45\,\lsim\, z\…
Cosmological Evolution of Quintessence and Phantom with a New Type of Interaction in Dark Sector
Hao Wei
In the present work, motivated by the work of Cai and Su [Phys. Rev. D {\bf 81}, 103514 (2010)], we propose a new type of interaction in dark sector, which can change its sign when…
Cosmological Constraints on the Modified Entropic Force Model
Hao Wei
Very recently, Verlinde considered a theory in which space is emergent through a holographic scenario, and proposed that gravity can be explained as an entropic force caused by cha…
Revisiting the Cosmological Constraints on the Interacting Dark Energy Models
Hao Wei
In this work, we consider the cosmological constraints on the interacting dark energy models. We generalize the models considered previously by Guo {\it et al.}, Costa and Alcaniz,…
Spinor Dark Energy and Cosmological Coincidence Problem
Hao Wei
Recently, the so-called Elko spinor field has been proposed to be a candidate of dark energy. It is a non-standard spinor and has unusual properties. When the Elko spinor field is…
