Non-extensive statistics to the cosmological lithium problem [PDF]

The Astrophysical Journal, 2017
Big Bang nucleosynthesis (BBN) theory predicts the abundances of the light elements D, 3He, 4He, and 7Li produced in the early universe. The primordial abundances of D and 4He inferred from observational data are in good agreement with predictions ...

Lamb Mossbauer factor using non-extensive Statistics [PDF]

Physics Letters A, 2003
Lamb Mossbauer factor is derived using Tsallis Statistics. Recoil free factor so obtained, has weak temperature dependence which is similar to the temperature dependence observed for Lamb Mossbauer factor of a fractalComment: 7 pages,2 figues.

Extensive Renyi Statistics from Non-Extensive Entropy [PDF]

Physics Letters A, 2004
We show that starting with either the non-extensive Tsallis entropy in Wang's formalism or the extensive Renyi entropy, it is possible to construct the equilibrium statistical mechanics with non-Gibbs canonical distribution functions.

Non-Extensive Quantum Statistics with Particle - Hole Symmetry [PDF]

Physica A: Statistical Mechanics and its Applications, 2014
Based on Tsallis entropy and the corresponding deformed exponential function, generalized distribution functions for bosons and fermions have been used since a while.

Non-extensive statistics and the stellar polytrope index

Physica A: Statistical Mechanics and its Applications, 2004
We use physical constrains imposed from the H-Theorem and from the negative nature of the heat capacity of self-gravitating thermodynamically isolated systems to investigate some possible limits on the stellar polytrope index $n$ within the domain of a ...

Cluster temperatures and non-extensive thermo-statistics [PDF]

New Astronomy, 2005
We propose a novel component to the understanding of the temperature structure of galaxy clusters which does not rely on any heating or cooling mechanism.

Non-Extensive Statistical Analysis of Seismicity on the West Coastline of Mexico

Fractal and Fractional
Mexico is a well-known seismically active country, which is primarily affected by several tectonic plate interactions along the southern Pacific coastline and by active structures in the Gulf of California.

Non-extensive statistics and slarr neutrinos [PDF]

Astrophysics and Space Science, 1997
In this paper we will show that, because of the long-range microscopic memory of the random force, acting in the solar core, mainly on the electrons and the protons than on the light and heavy ions (or, equally, because of anomalous diffusion of solar core constituents of light mass and of normal diffusion of heavy ions), the equilibrium statistical ...
