Entropic corrections and modified Friedmann equations in the emergence of cosmic space

摘要: In the emergent cosmic space scenario recently proposed by Padmanabhan, expansion of universe is attributed to difference between number degrees freedom on a holographic surface and one in bulk. Based this idea, we explore cases where logarithmic power-law entropic corrections are present, respectively. The previously found modified Friedmann equations reproduced through an improved proposal, show that same results can be obtained using generalized law.
