View source for Nonextensive entropy

{{unreferenced|date=September 2011}}

[[Entropy]] is considered to be an [[extensive property]], i.e., that its value depends on the amount of material present. [[Constantino Tsallis]] has proposed a '''nonextensive entropy''' ([[Tsallis entropy]]), which is a generalization of the traditional [[Boltzmann's entropy formula|Boltzmann–Gibbs entropy]].

The rationale behind the theory is that Gibbs-Boltzmann entropy leads to systems that have a strong dependence on [[initial conditions]]. In reality most materials behave quite independently of initial conditions.

Nonextensive entropy leads to nonextensive [[statistical mechanics]], whose typical functions are [[power law]]s, instead of the traditional [[Exponential function|exponential]]s.
