Abstract

It is shown that the standard formula for the pressure of a gas of free massless fermions leads to negative probabilities when the fermion number of the system being equal to n if n is large. The ways of resolving this paradox are proposed. A detailed analysis of the corresponding partition function reveals the existence of the Roberge–Weiss transition in the absence of strong interactions.

高温夸克气体：有限体积效应

结果表明，当系统的费米子数等于n时，如果n较大，由自由无质量费米子组成的气体的压力的标准公式导致负概率。提出了解决这一矛盾的方法。对相应配分函数的详细分析表明，在没有强相互作用的情况下，存在Roberge-Weiss跃迁。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
