Abstract

Development of nano-technology throws a new challenge to statistical physics. The classical statistical physics is underlaid by classical or quantum mechanics of closed systems, classical version of the Central Limit Theorem, the Markov model of Brownian motion, the linear approximation of the perturbation theory as a main mathematical tool. The nanotechnology has caused constructing new models: nonlocal in space and time dynamics, generalized Limit Theorem for the Levy-stable family as limit distributions, non-Markovian (subordinated) Levy-motion and instead of the Brownian one, self-similar (fractal) and non-local (integral and fractional differential) analysis. The article gives a short review of these concepts. The multiscale complex system is considered to exacute a selfsimilar motion obeying the Levy stable statistics, which generalized then to fractionally stable kind. The intermediate asymptotics is introduced on the base of truncated Lévy flight. This leads to the correspondence principle connecting classical and nano-statistics. Some numerical results are presented.
