基于相对熵最大化的相对论平衡分布

Relativistic Equilibrium Distribution by Relative Entropy Maximization

Tadas K Nakamura

摘要:

根据最大熵原理计算了相对论气体的平衡态。虽然相对论平衡态长期以来被认为是Juttner分布,但近年来发表了许多论文,提出了替代的平衡态。然而,其中有些文献对分布函数的协方差性没有给予足够的重视,造成了对平衡态的混淆。从一个完全协变的表达式,以避免这种混乱,它已被证明在本文中,Juttner分布是最大熵状态,如果我们假设的洛伦兹对称性。

英文摘要:

The equilibrium state of a relativistic gas has been calculated based on the maximum entropy principle. Though the relativistic equilibrium state was long believed to be the Juttner distribution, a number of papers have been published in recent years proposing alternative equilibrium states. However, some of these papers do not pay enough attention to the covariance of distribution functions, resulting confusion in equilibrium states. Starting from a fully covariant expression to avoid this confusion, it has been shown in the present paper that the Juttner distribution is the maximum entropy state if we assume the Lorentz symmetry.
