The hydrostatic equilibrium and Tsallis equilibrium for self-gravitating systems
, 2004 Self-gravitating systems are generally thought to behavior non-extensively due to the long-range nature of gravitational forces. We obtain a relation between the nonextensive parameter q of Tsallis statistics, the temperature gradient and the ...

Is Tsallis thermodynamics nonextensive? [PDF]
, 2001 Within the Tsallis thermodynamics' framework, and using scaling properties of the entropy, we derive a generalization of the Gibbs-Duhem equation. The analysis suggests a transformation of variables that allows standard thermodynamics to be recovered ...

Equivalence of the four versions of Tsallis’s statistics [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2005 In spite of its undeniable success, there are still open questions regarding Tsallis non-extensive statistical formalism, whose founding stone was laid in 1988 in JSTAT. Some of them are concerned with the so-called normalization problem of just how to evaluate expectation values.

Special Issue: Tsallis Entropy
Entropy, 2012 One of the crucial properties of the Boltzmann-Gibbs entropy in the context of classical thermodynamics is extensivity, namely proportionality with the number of elements of the system.

Physics Letters B, 2022 In this work we have investigated the effects of three nongaussian entropies, namely, the modified Rényi entropy (MRE), the Sharma-Mittal entropy (SME) and the dual Kaniadakis entropy (DKE) in the investigation of the generalized second law (GSL) of ...

Lattice QCD thermodynamics and RHIC-BES particle production within generic nonextensive statistics
, 2017 The current status of implementing Tsallis (nonextensive) statistics on high-energy physics is briefly reviewed. The remarkably low freezeout-temperature, which apparently fails to reproduce the first-principle lattice QCD thermodynamics and the measured

Quasicanonical Gibbs distribution and Tsallis non-extensive statistics [PDF]
Physica A: Statistical Mechanics and its Applications, 2003 We derive and study quasicanonical Gibbs distribution function which is characterized by the thermostat with finite number of particles (quasithermostat). We show that this naturally leads to Tsallis nonextensive statistics and thermodynamics, with Tsallis parameter q is found to be related to the number of particles in the quasithermostat.

Channel Capacity of Coding System on Tsallis Entropy and q-Statistics
Entropy, 2017 The field of information science has greatly developed, and applications in various fields have emerged. In this paper, we evaluated the coding system in the theory of Tsallis entropy for transmission of messages and aimed to formulate the channel ...

Astrophysical thermonuclear functions for Boltzmann–Gibbs statistics and Tsallis statistics [PDF]
Physica A: Statistical Mechanics and its Applications, 2004 We present an analytic proof of the integrals for astrophysical thermonuclear functions which are derived on the basis of Boltzmann-Gibbs statistical mechanics. Among the four different cases of astrophysical thermonuclear functions, those with a depleted high-energy tail and a cut-off at high energies find a natural interpretation in q-statistics.

Dynamical Origin of Power Spectra
, 2008 We discuss a possible origin of Tsallis' statistics from the correlation among constituents which reduces the phase space of the system. We also show that in the system of coupled linear harmonic oscillators can exhibit a Tsallis type behavior.Comment ...
