Interacting Ricci Logarithmic Entropy Corrected Holographic Dark Energy in Brans-Dicke Cosmology

摘要

In the derivation of Holographic Dark Energy (HDE), the area law of the blackhole entropy assumes a crucial role. However, the entropy-area relation can bemodified including some quantum effects, motivated from the Loop QuantumGravity (LQG), string theory and black hole physics. In this paper, we studythe cosmological implications of the interacting logarithmic entropy-correctedHDE (LECHDE) model in the framework of Brans-Dicke (BD) cosmology. As system'sinfrared (IR) cut-off, we choose the average radius of Ricci scalar curvature,i.e. $R^{-1/2}$. We obtain the Equation of State (EoS) parameter $\omega_D$,the deceleration parameter $q$ and the evolution of energy density parameter$\Omega'_D$ of our model in a non-flat universe. Moreover, we study thelimiting cases corresponding to our model without corrections and to theEinstein's gravity.
