An Application of Non-Extensive Statistical Mechanics to Nanosystems

Non-extensive statistical mechanics approach to fully developed hydrodynamic turbulence

We apply non-extensive methods to the statistical analysis of fully developed turbulent flows. Probability density functions of velocity differences at distance r obtained by extremizing the Tsallis entropies coincide well with what is measured in turbulence experiments. We derive a set of relations between the hyperflatness factors Fm and the non-extensitivity parameter q, which can be used to...

Scale Invariance and Symmetry Relationships In Non-Extensive Statistical Mechanics

This article extends results described in a recent article detailing a structural scale invariance property of the simulated annealing (SA) algorithm. These extensions are based on generalizations of the SA algorithm based on Tsallis statistics and a non-extensive form of entropy. These scale invariance properties show how arbitrary aggregations of energy levels retain certain mathematical char...

Dark matter distribution function from non-extensive statistical mechanics

We present an analytical and numerical study of the velocity distribution function of self gravitating collisionless particles, which include dark matter and star clusters. We show that the velocity distribution derived through the Eddington’s formula is identical to the analytical one derived directly from the generalized entropy of non-extensive statistical mechanics. This implies that self g...

Non-extensive statistical mechanics and particle spectra in elementary interactions

We generalize Hagedorn’s statistical theory of momentum spectra of particles produced in high-energy collisions using Tsallis’ formalism of non-extensive statistical mechanics. Suitable non-extensive grand canonical partition functions are introduced for both fermions and bosons. Average occupation numbers and moments of transverse momenta are evaluated in an analytic way. We analyse the energy...
