Abstract
Este trabajo tiene como objetivo determinar si existe algún grado de correlación entre los fotones de una cavidad radiante utilizando la ley de radiación generalizada obtenida según el formalismo de la Mecánica Estadística No Extensiva. Para tal efecto, se usaron resultados de publicaciones sobre la ley generalizada de la radiación de cuerpo negro, con base a las cuales se estimó un índice entrópico q muy proximo a uno (q = 0.9999), coincidiendo con investigaciones similares. Se realizó la evaluación numérica del modelo generalizado y se lo comparó con el modelo convencional de Planck para dos temperaturas diferentes: 2,75 K (radiación cosmica de fondo) y 5777 K (radiación solar). En el primer caso se vio que para que el modelo generalizado se ajuste mejor a los datos que el modelo de Planck, era necesario un valor de q aún más proximo a la unidad. En el segundo caso, sin embargo, con q = 0.9999 se obtuvo un mejor ajuste que con el modelo de Planck. Esta comparación condujo a dos conclusiones: 1) A temperaturas bajas la correlación fotónica es muy debil o simplemente no existe. 2) A medida que se incrementa la temperatura, podría comenzar a aparecer, levemente, cierta correlación , expresada en un valor de q que difiere cada vez más de la unidad.
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.
