R\'enyi entropy for particle systems as an instrument to enlarge the Boltzmannian concept of entropy: some holographic perspectives
2015
The R\'enyi entropy is a mathematical generalization of the concept of entropy and it encodes the total information of a system as a funtion of its order parameter $\alpha$. The meaning of the R\'enyi entropy in physics is not completely enstablished: here we determined a general and explicit representation of the R\'enyi entropy for whichever fluid of particles and spin-statistics, in the mechanical statistics framework. This allowed us to put physical constraints to the R\'enyi order $\alpha$, from main thermodynamical relations and entropy bounds of the holographic theories, defining how much we can enlarge the Boltmannian concept of entropy.
