Non-extensive statistical mechanics and the thermodynamic stability of FRW universe

چکیده
In this article, we investigate the thermodynamic stability of FRW universe for two examples, Tsallis entropy and loop quantum gravity, by considering non-extensive statistical mechanics. The heat capacity, free energy pressure are obtained. For model, obtained constraint $\beta$, namely, $1/2 < \beta 2$. a thermal equilibrium must be less than zero. We suggest that reason accelerated expansion is not due to entropy. Similar results gravity. However, since values $\Lambda(\gamma)$ $q$ cannot determined in become more subtle model. addition, compare with those Schwarzschild black hole.

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...
متن کاملNon-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...
متن کاملNon-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...
متن کاملDark 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...
متن کاملThermodynamic Behavior of Friedmann Equations at Apparent Horizon of FRW Universe
It is shown that the differential form of Friedmann equations of a FRW universe can be rewritten as a thermodynamical identity T dS = dE + P dV at apparent horizon, where E is the Misner-Sharp energy, V is the volume inside the apparent horizon, and P is the pressure of the perfect fluid in the universe. From the thermodynamic identity one can derive that the apparent horizoñ r A has associated...
