关于宇宙中退耦物质的化学势的注记
Note on the chemical potential of decoupled matter in the Universe
摘要:
宇宙学的教科书展示了自由流动、解耦物质的热力学不一致性。它在这里与化学势有关,化学势偏离其平衡值$μ=αk_BT$,其中$α$是费米-狄拉克或玻色-爱因斯坦分布函数的常用参数。
英文摘要:
Textbooks on cosmology exhibit a thermodynamic inconsistency for free streaming, decoupled matter. It is connected here to the chemical potential, which deviates from its equilibrium value $μ=αk_BT$, where $α$ is the usual parameter of the Fermi-Dirac or Bose-Einstein distribution function.
