相对论动力学和幂律尾分布

Relativistic kinetics and power-law tailed distributions

G. Kaniadakis

摘要:

本文介绍了在Phys. Rev. E { \bf 66}(2002)056125和Phys. Rev. E { \bf 72}(2005)036108中介绍的相对论统计理论,用$\exp_κ(x)=(\sqrt{1+ κ^2 x^2}+κx)^{1/κ}$和$κ^2<1$预测粒子分布函数$p(E)= \exp_κ (-β[E-μ])$。实验观察到,相对论分布,在低能量下表现为指数,麦克斯韦-玻尔兹曼经典分布,而在高能量下呈现幂律尾。在这里,我们得到的演化方程,进行渐近上述分布,通过使用一个新的演绎程序,从相对论BBGKY系列和采用相对论分子混沌假设。

英文摘要:

The present paper is devoted to the relativistic statistical theory, introduced in Phys. Rev. E {\bf 66} (2002) 056125 and Phys. Rev. E {\bf 72} (2005) 036108, predicting the particle distribution function $p(E)= \exp_κ (-β[E-μ])$ with $\exp_κ(x)=(\sqrt{1+ κ^2 x^2}+κx)^{1/κ}$, and $κ^2<1$. This, experimentally observed, relativistic distribution, at low energies behaves as the exponential, Maxwell-Boltzmann classical distribution, while at high energies presents power law tails. Here, we obtain the evolution equation, conducting asymptotically to the above distribution, by using a new deductive procedure, starting from the relativistic BBGKY hierarchy and by employing the relativistic molecular chaos hypothesis.
