Nonextensive statistical field theory

چکیده

We introduce a field-theoretic approach for describing the critical behavior of nonextensive systems, systems displaying global correlations among their degrees freedom, encoded by parameter q. As some applications, we report, to our knowledge, first analytical computation both universal static and dynamic q-dependent exponents O(N) vector models, valid all loop orders |q−1|<1. Then emerges new O(N)q universality class. Both ηq zq reduce those when q=1 N→∞. employ six independent methods which furnish identical results. Particularly, results 2d Ising exact within referred approximation, agree with that obtained from computer simulations, margin error, as better q is closer 1. argue present can be applied models described extensive statistical field theory well. The show an interplay between fluctuations.

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...

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...

Classical and Nonextensive Information Theory

Information theory deals with measurement and transmission of information through a channel. A fundamental work in this area is the Shannon’s Information Theory (see [2], Chapter 11), which provides many useful tools that are based on measuring information in terms of the complexity of structures needed to encode a given piece of information. Shannon’s theory solves two central problems for cla...

Trace inequalities in nonextensive statistical mechanics

In this short paper, we establish a variational expression of the Tsallis relative entropy. In addition, we derive a generalized thermodynamic inequality and a generalized Peierls-Bogoliubov inequality. Finally we give a generalized Golden-Thompson inequality.
