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 …

Spherically symmetric time-dependent solutions for the 5D system of a scalar field
canonically coupled to gravity are obtained and identified as an extension of recent results …

The Dirac equation describes the dynamics of a relativistic spin-1/2 particle regarding its
spatial motion and intrinsic degrees of freedom. Here we adopt the point of view that the …

In cosmology, phenomenologically motivated expressions for running vacuum are
commonly parameterized as linear functions typically denoted by Λ (H 2) or Λ (R). Such …

We apply concepts from the quantum measurement theory to obtain some cosmological
neutrino background (CνB) properties and discuss their relevance in defining theoretical …

Modifications on the predictions about the matter power spectrum based on the hypothesis
of a tiny contribution from a degenerate Fermi gas (DFG) test-fluid to some dominant …

Damping of primordial gravitational waves due to the anisotropic stress contribution owing to
the cosmological neutrino background (C] B) is investigated in the context of a radiation-to …

Na primeira parte deste trabalho descrevemos os neutrinos cosmológicos como um sistema
quântico composto e utilizamos a teoria generalizada das medidas quânticas para obter …

Neste trabalho nós estudamos a evoluçao de ondas gravitacionais primordiais acopladas
ao tensor de stress anisotrópico dos neutrinos cosmológicos. Assim como em um universo …
