SOME OPEN POINTS IN NONEXTENSIVE STATISTICAL MECHANICS

Some Open Points in Nonextensive Statistical mechanics

Statistical mechanics is one of the pillars of contemporary physics. Indeed, it provides in principle the link between the microscopic and the macroscopic description and understanding of the world through a rich variety of mesoscopic instances. More precisely, starting from mechanics (classical, quantum, relativistic) and electromagnetism, it incorporates appropriate concepts of the theory of ...

Duality in nonextensive statistical mechanics.

We revisit recent derivations of kinetic equations based on Tsallis' entropy concept. The method of kinetic functions is introduced as a standard tool for extensions of classical kinetic equations in the framework of Tsallis' statistical mechanics. Our analysis of the Boltzmann equation demonstrates a remarkable relation between thermodynamics and kinetics caused by the deformation of macroscop...

BEC in Nonextensive Statistical Mechanics: Some Additional Results

In a recent paper [Int. J. Mod. Phys. B 14, 405 (2000)] we discussed the Bose-Einstein condensation (BEC) in the framework of Tsallis’s nonextensive statistical mechanics. In particular, we studied an ideal gas of bosons in a confining harmonic potential. In this memoir we generalize our previous analysis by investigating an ideal Bose gas in a generic power-law external potential. We derive an...

Nonextensive statistical mechanics and economics

Ergodicity, this is to say, dynamics whose time averages coincide with ensemble averages, naturally leads to Boltzmann-Gibbs (BG) statistical mechanics, hence to standard thermodynamics. This formalism has been at the basis of an enormous success in describing, among others, the particular stationary state corresponding to thermal equilibrium. There are, however, vast classes of complex systems...
