Emergent cosmology in models of nonlinear electrodynamics

چکیده
Nonlinear electrodynamics, which acts as a source of gravity Einstein field equations, leads to emergent cosmology, an alternative solution can avoid Big Bang singularity. In this paper, we explore the emerging universe in models non-linear electrodynamics (described by dimensional parameter $\beta$) using equation state $\omega$ and see how $\beta$ helps cause transition from quasi-static Minkowski phase inflationary expansion through point emergence subsequently normal thermal expansion. We predict spectral index $n_s = 0.97467$ (scalar index), $r =0.10133$ (tensor scalar ratio) $n_T -0.01267$ index) perturbation cosmology nonlinear corresponding 0.1 $B_0=10^{-10}$G.

Emergent Time Windows in Nonlinear Neural Models
In order to study how n to 1 convergence sharpens timing information, we have used a simple time-window (TW) model in which the target neuron fires the first time it has received m action potentials in the previous εmilleseconds. Although the TW is convenient for proving theorems and Monte-Carlo simulations, it is a natural question whether it represents well the physiological reality. We first...
متن کاملTime Asymmetry in Electrodynamics and Cosmology
The concept of the barrow of time' is discussed in relation to thermodynamics, electrodynamics and cosmology Time symmetric electrodynamics, the absorber theory of radiation and quantum transitions receive attention to develop a working theory applicable to a universe with a perfect future absorber and an imperfect past absorber, such as the steady state cosmological model. It is stated that th...
متن کاملNonlinear stability of homogeneous models in Newtonian cosmology
We consider the Vlasov-Poisson system in a cosmological setting as studied in [18] and prove nonlinear stability of homogeneous solutions against small, spatially periodic perturbations in the L∞-norm of the spatial mass density. This result is connected with the question of how large scale structures such as galaxies have evolved out of the homogeneous state of the early universe.
متن کاملNonlinear noise in cosmology.
This paper derives and analyzes exact, nonlocal Langevin equations appropriate in a cosmological setting to describe the interaction of some collective degree of freedom with a surrounding “environment.” Formally, these equations are much more general, involving as they do a more or less arbitrary “system,” characterized by some time-dependent potential, which is coupled via a nonlinear, time-d...
متن کاملCosmology of Nonlinear Oscillations
The nonlinear oscillations of a scalar field are shown to have cosmological equations of state with w = p/ρ ranging from −1 < w < 1. We investigate the possibility that the dark energy is due to such oscillations. ∗[email protected]
