ANDRADE, M. J. y VISCARRA, M. A.. STUDY OF THE PHOTONIC CORRELATION FOUND IN THE RADIANT CAVITY USING NON EXTENSIVE STATISTICAL MECHANICS. Revista Boliviana de Física [online]. 2009, vol.15, n.15, pp.14-17. ISSN 1562-3823.
This study seeks to determine if there exists a correlation between the photons of a radiant cavity using the generalized law of radiation obtained from non extensive statistical mechanics. Results were used from publications on the general radiation law of black body to estimate an entropic index q close to the unit (q= 0.9999). These coincide with similar studies. A numerical evaluation of the generalized model was carried out and compared with the conventional Planck model for two different temperatures: 2,75 K (lower cosmic radiation) and 5777 K (solar radiation). In the first case it was found that the generalized model adjusts better to the data than the Planck model. A value q, even closer to the unit, was needed. In the second case with a value of q = 0.9999 a better adjustment to the data was found compared to the Planck model. The following conclusions were drawn from these results: 1) At lower temperatures the photonic correlation is very weak or non existent. 2) With an increase in temperature a slight correlation expressed by q is seen which differs more each time from the unit.
