Quantal distribution functions in non-extensive statistics and an early universe test revisited
Within the context of non-extensive thermostatistics, we use the
factorization approximation to study a recently proposed early universe test. A
very restrictive bound upon the non-extensive parameter is presented: .Comment: 4 pages, prl revtex style, no figures. To appear in Physica A, 199
Generalized Distribution Functions and an Alternative Approach to Generalized Planck Radiation Law
In this study, recently introduced generalized distribution functions are
summarized and by using one of these distribution functions, namely generalized
Planck distribution, an alternative approach to the generalized Planck law for
the blackbody radiation has been tackled.Comment: 13 pages, RevTeX, 1 fi

When Brownian diffusion is not Gaussian
It is commonly presumed that the random displacements that particles undergo as a result of the thermal jiggling of the environment follow a normal, or Gaussian, distribution. Here we reason, and support with experimental examples, that non-Gaussian diffusion in soft materials is more prevalent than expected.close442
