Modified Holographic Dark Energy

Abstract

In this work, motivated by the energy bound suggested by Cohen {\it et al.}, we propose the modified holographic dark energy (MHDE) model. Choosing the IR cut-off $L=R_{\mathrm{CC}}$ and considering the parameterizations $n^2=2-\lambda a$, $n^2=2-3\lambda a^2/(1+3a^2)$ and $n^2=2-\lambda a^2/(\beta +a^2)$, we derive all the physical quantities of the non-saturated MHDE model analytically. We find that the non-saturated MHDE models with the parameterizations $n^2=2-\lambda a$ and $n^2=2-3\lambda a^2/(1+3a^2)$ are single-parameter models in practice. Also, we consider the cosmological constraints on the non-saturated MHDE, and find that it is well consistent with the observational data.
