Modified holographic dark energy Original Research Article

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 image and considering the parameterizations image, image and image, we derive all the physical quantities of the non-saturated MHDE model analytically. We find that the non-saturated MHDE models with the parameterizations image and image 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.
