Quasi-additivity of Tsallis entropies and correlated subsystems
arXiv:0705.0888 · doi:10.1016/j.physa.2007.02.033
Abstract
We use Beck's quasi-additivity of Tsallis entropies for $n$ independent subsystems to show that like the case of $n=2$, the entropic index $q$ approaches 1 by increasing system size. Then, we will generalize that concept to correlated subsystems to find that in the case of correlated subsystems, when system size increases, $q$ also approaches a value corresponding to the additive case.
