On entropic cosmology, late time acceleration and the quantum bounce
In this work, we present a unified entropic description of the quantum bounce that is present in Loop Quantum Cosmology (LQG) and dark energy that drives the late time acceleration of the Universe. By considering a minimal area $A_0$ for the Universe and a modified entropy area constructed as the sum of $S_Q$, $S_{BH}$ and $S_{DE}$, we derive the Friedmann equations. We show that in the limit $A\sim A_0$, there is a critical density that generates the quantum bounce and depends on the minimal area. Moreover, in the limit $A\gg A_0$ (large Universe) the late time dynamics gives an accelerating scale factor. Therefore, we can argue an entropic origin for the quantum bounce and dark energy.
