Abstract

It has been shown that a functional dependence of the configurational entropy (CE) density exhibits a cosmological comoving behavior related to the scale parameter, a, of the FRW flat universe. Such a circumstantial comoving behavior shows that the CE evolves with a(-3) for fermionic and bosonic radiation and with a(-3/2) for non-relativistic fermionic matter. The results are discussed in the domain of matter and radiation, as well as in a simplified context of the ACDM cosmology. Our results suggest that the CE can work as a theoretical driver for particle and nuclear interactions in the context of large scale cosmic events. (C) 2019 The Authors. Published by Elsevier B.V.
