A possible correction of the Saha curve for non-equilibrium states
L. L. Sales, F. C. Carvalho, H. T. C. M. Souza
It is widely known that the Saha equation is not suitable for describing plasmas out of thermodynamic equilibrium. The primordial hydrogen recombination plasma is an example of thi…
Constraint on the chemical potentials of hydrogen and proton in recombination
L. L. Sales, F. C. Carvalho, H. T. C. M. Souza
In this paper, we revisit the hydrogen recombination history from a novel perspective: the evolution of chemical potentials. We derive expressions for the chemical potentials, whic…
Non-Gaussian Effects of the Saha's Ionization in the Early Universe
L. L. Sales, F. C. Carvalho, E. P. Bento +1
Tsallis' thermostatistical has received increasing attention due to its success in describing phenomena that manifest unusual thermodynamic properties. In this context, the general…
An alternative method for solving the Gaussian integral
Lázaro L. Sales, Jonatas A. Silva, Eliângela P. Bento +3
In this paper, we have proposed a new method for solving the Gaussian integral. Introducing a parameter that depends on a index, we have found a general solution for this type…
Coupling dark-baryonic matter density profile for vacuum decay scenarios
H. T. C. M. Souza, N. Pires, F. E. M. Costa +2
The cosmological consequences of an interacting model in which vacuum decay law is deducted from the effect that vacuum decay has on the dark matter evolution are investigated. Her…
