英文摘要：

In this paper, we have analyzed the nonextensive Tsallis statistical mechanics in the light of Verlinde's formalism. We have obtained, with the aid of a noncommutative phase-space entropic gravity, a new bound for Tsallis nonextensive (NE) parameter (TNP) that is clearly different from the ones present in the current literature. We derived the Friedmann equations in a NE scenario. We also obtained here a relation between the gravitational constant and the TNP.

非对易空间中的Landau抗磁性和Tsallis非广延热力学

Landau Diamagnetism in Noncommutative Space and the Nonextensive Thermodynamics of Tsallis

本文考虑电子在外部均匀磁场B中的行为，其中垂直于B的空间坐标取为非对易。这导致了标准热力学的一般化。计算磁化率，我们发现通常的朗道抗磁性被修改。我们还根据Tsallis的非广延统计量（1-q）<<1，在因式分解的方法计算的易感性。两种方法在一定条件下是一致的。

非广延Tsallis统计中的量子场论

Quantum Field Theories in Nonextensive Tsallis Statistics

在q ~ 1的Tsallis统计量的框架内，我们构造了一个处理相对论量子场系统的微扰理论。我们发现，出现了初始相关，这是不存在的Boltzmann-Gibbs统计。把这个框架应用到夸克-胶子等离子体中，我们发现夸克和胶子的所谓热质量比玻尔兹曼-吉布斯统计的情况要小。

Fundamental Constants, Entropic Gravity and Nonextensive Equipartition Theorem

By using the Verlinde's formalism[1], we propose that the positive numerical factor, in which Klinkhamer[2] states that it is necessary to define the fundamental length, can be associated to the parameter q of the Tsallis' nonextensive statistical mechanics[3].

The minimal length uncertainty and the nonextensive thermodynamics

In this paper, we study the thermodynamics of quantum harmonic oscillator in the Tsallis framework and in the presence of a minimal length uncertainty. The existence of the minimal length is motivated by various theories such as string theory, loop quantum gravity, and black-hole physics. We analytically obtain the partition function, probability function, internal energy, and the specific heat capacity of the vibrational quantum system for $1<q<\frac{3}{2}$ and compare the results with those of Tsallis and Boltzmann-Gibbs statistics without the minimal length scale.

Phase transition for the system of small volume in the $ϕ^4$ theory in the Tsallis nonextensive statistics

We studied the effects of the nonextensivity on the phase transition for the system of small volume $V$ in the $ϕ^4$ theory in the Tsallis nonextensive statistics of entropic parameter $q$ and temperature $T$, when the deviation from the Boltzmann-Gibbs statistics, $|q-1|$, is small. We calculated the condensate and the mass to the order $q-1$ with the normalized $q$-expectation value under the massless free particle approximation. The following facts were found. The condensate $Φ$ divided by $v$, $Φ/v$, at $q$ is smaller than that at $q'$ for $q>q'$ as a function of $T_{\mathrm{ph}}/v$ which …

Nonextensive statistics, entropic gravity and gravitational force in a non-integer dimensional space

Based on the connection between Tsallis nonextensive statistics and fractional dimensional space, in this work we have introduced, with the aid of Verlinde's formalism, the Newton constant in a fractal space as a function of the nonextensive constant. With this result we have constructed a curve that shows the direct relation between Tsallis nonextensive parameter and the dimension of this fractal space. We have demonstrated precisely that there are ambiguities between the results due to Verlinde's approach and the ones due to fractional calculus formalism. We have shown precisely that these a…

Holographic dark energy through Tsallis entropy

In order to apply holography and entropy relations to the whole universe, which is a gravitational and thus nonextensive system, for consistency one should use the generalized definition for the universe horizon entropy, namely Tsallis nonextensive entropy. We formulate Tsallis holographic dark energy, which is a generalization of standard holographic dark energy quantified by a new dimensionless parameter $δ$, possessing the latter as a particular sub-case. We provide a simple differential equation for the dark energy density parameter, as well as an analytical expression for its equation-of-…

Modifications of CMB spectrum by nonextensive statistical mechanics

Cosmic microwave background radiation can supply us some most significant parts of the information on the universe. Some researchers believe that The gravitational system cannot be decribed by the standard statistical mechanics. In this article we apply Tsallis nonextensive statistical mechanics to investigate CMB spectrum and related cosmological processes. Based on recent observational data we find that the nonextensive statistical mechanics can modify the values of related physical quantites. Since the value of physical quantites have changed, some processes, such as recombination, can be a…

Chemical freezeout parameters within generic nonextensive statistics

The particle production in relativistic heavy-ion collisions seems to be created in a dynamically disordered system which can be best described by an extended exponential entropy. In distinguishing between the applicability of this and Boltzmann-Gibbs (BG) in generating various particle-ratios, generic (non)extensive statistics (GNS) is introduced to the hadron resonance gas model. Accordingly, the degree of (non)extensivity is determined by the possible modifications in the phase space. Both BG extensivity and Tsallis nonextensivity are included as very special cases defined by specific value…
