摘要

In this work, motivated by the energy bound suggested by Cohen et al., we propose the modified holographic dark energy (MHDE) model. Choosing the IR cut-off L = R CC and considering the parameterizations n 2 = 2 - λ a, n 2 = 2 - 3 λ a 2 / (1 + 3 a 2) and n 2 = 2 - λ a 2 / (β + 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 - λ a and n 2 = 2 - 3 λ a 2 / (1 + 3 a 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.
