Possible theoretical limits on holographic quintessence from weak gravity conjecture
Yin-Zhe Ma, Xin Zhang
The holographic dark energy model is one of the important ways for dealing with the dark energy problems in the quantum gravity framework. In this model, the dimensionless paramete…
Holographic tachyon model
Jingfei Zhang, Xin Zhang, Hongya Liu
We propose in this Letter a holographic model of tachyon dark energy. A connection between the tachyon scalar-field and the holographic dark energy is established, and accordingly,…
Constraints on Holographic Dark Energy from Latest Supernovae, Galaxy Clustering, and Cosmic Microwave Background Anisotropy Observations
Xin Zhang, Feng-Quan Wu
The holographic dark energy model is proposed by Li as an attempt for probing the nature of dark energy within the framework of quantum gravity. The main characteristic of holograp…
Reconstructing generalized ghost condensate model with dynamical dark energy parametrizations and observational datasets
Jingfei Zhang, Xin Zhang, Hongya Liu
Observations of high-redshift supernovae indicate that the universe is accelerating at the present stage, and we refer to the cause for this cosmic acceleration as ``dark energy''.…
