物理相关性导致Kappa分布
Physical correlations lead to kappa distributions
摘要：
最近发展起来的“熵亏损”概念对于理解空间等离子体物理学中的热力学基础，更一般地说，对于粒子之间具有物理关联的系统，是很重要的。利用这一概念，本文导出了空间等离子体粒子群速度（或动能）分布函数的基本公式。早期的分析已经表明，卡帕分布的公式是如何与粒子速度之间的相关性交织在一起的。本文第一次表明，相反的情况是正确的：粒子的物理关联的热力学是一致的，只有存在的卡帕分布。
英文摘要：
The recently developed concept of "entropic defect" is important for understanding the foundations of thermodynamics in space plasma physics, and more generally, for systems with physical correlations among their particles. Using this concept, this paper derives the basic formulation of the distribution function of velocities (or kinetic energies) in space plasma particle populations. Earlier analyses have shown how the formulation of kappa distributions is interwoven with the presence of correlations among the particles' velocities. This paper shows, for the first time, that the reverse is true: the thermodynamics of particles' physical correlations are consistent only with the existence of kappa distributions.
