Emergence of space and cosmic evolution based on entropic force    [PDF]

Fei-Quan Tu, Yi-Xin Chen

From the perspective of the hologram, our universe is asymptotically holographic. We propose an additional pressure is added to the ideal fluid since the effects of the entropic force. Furthermore, we obtain the dynamic equation in FRW universe which contains the quantum gravitational effects based on the description of entropic force and emergence of space. Our model can well explain the age of the universe and current accelerating expansion. We give the relation between the luminosity distance and the redshift factor, and compare it with that of lambda cold dark matter model($\Lambda CDM$ model). It may cause inflation when the quantum effects are considered at very early universe. At last, we think the entropic force caused by the surface term may be the origin of the "dark energy".
