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

Abstract

In the derivation of Holographic Dark Energy (HDE), the area law of the black hole entropy assumes a crucial role. However, the entropy-area relation can be modified including some quantum effects, motivated from the Loop Quantum Gravity (LQG), string theory and black hole physics. In this paper, we study the cosmological implications of the interacting logarithmic entropy-corrected HDE (LECHDE) model in the framework of Brans-Dicke (BD) cosmology. As system's infrared (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 the limiting cases corresponding to our model without corrections and to the Einstein's gravity.
