The kappa parameter and kappa-distribution in kappa-deformed statistics for the systems in an external field
Lina Guo, Jiulin Du
The kappa-deformed statistics has been studied in many papers. It is naturally important question for us to ask what should the kappa parameter stand for and under what physical si…
The difference of boundary effects between Bose and Fermi systems
Hai Pang, Wu-Sheng Dai, Mi Xie
In this paper, we show that there exists an essential difference of boundary effects between Bose and Fermi systems both for Dirichlet and Neumann boundary conditions: at low tempe…
Nonextensivity and the power-law distributions for the systems with self-gravitating long-range interactions
Jiulin Du
By a natural nonextensive generalization of the conservation of energy in the q-kinetic theory, we study the nonextensivity and the power-law distributions for the many-body system…
The equation of state for two-dimensional hard-sphere gases: Hard-sphere gases as ideal gases with multi-core boundaries
Wu-Sheng Dai, Mi Xie
The equation of state for a two-dimensional hard-sphere gas is difficult to calculate by usual methods. In this paper we develop an approach for calculating the equation of state o…
Test of Nonextensive Statistical Mechanics by Solar Sound Speeds
Jiulin Du
To check the validity of the theory of nonextensive statistical mechanics, we have investigated the nonextensive degree of the solar interior and have tried to find the experimenta…
The Chandrasekhar condition of the equilibrium and stability for a star in the nonextensive kinetic theory
Jiulin Du
The idea of Chandrasekhar condition of the equilibrium and stability for a star is revisited in the nonextensive kinetic theory based on Tsallis entropy. A new analytical formula g…
