Superstatistics and Gravitation
We suggest to consider the spacetime as a non-equilibrium system with a long-term stationary state that possess as a spatio-temporally fluctuating quantity β. These systems can be described by a superposition of several statistics, “superstatistics”. We propose a Gamma distribution for f(β) that depends on a parameter pl. By means of it the corresponding entropy is calculated, pl is identified ...
متن کاملSuperstatistics: Theory and Applications
Superstatistics is a superposition of two different statistics relevant for driven nonequilibrium systems with a stationary state and intensive parameter fluctuations. It contains Tsallis statistics as a special case. After briefly summarizing some of the theoretical aspects, we describe recent applications of this concept to three different physical problems, namely a) fully developed hydrodyn...
متن کاملSuperstatistics, thermodynamics, and fluctuations.
A thermodynamiclike formalism is developed for superstatistical systems based on conditional entropies. This theory takes into account large-scale variations of intensive variables of systems in nonequilibrium stationary states. Ordinary thermodynamics is recovered as a special case of the present theory, and corrections to it can systematically be evaluated. A generalization of Einstein's rela...
متن کاملSuperstatistics, thermodynamics, and temperature variations
A thermodynamic-like formalism is developed for superstatistical systems based on conditional entropies. This theory takes into account large-scale temperature variations for systems in nonequilibrium stationary states. Ordinary thermodynamics is recovered as a special case of the present theory, and corrections to it can be systematically evaluated. A generalization of Einstein’s relation for ...
متن کاملSuperstatistics, escort distributions, and applications
Superpositions of different statistics on different time or spatial scales (in short, superstatistics) can naturally lead to an effective description by nonextensive statistical mechanics. We first discuss the role of escort distributions within the superstatistical framework, and then briefly describe recent physical applications of this concept to turbulent and patttern forming systems.
