...Furthermore, even in a multi-particle system without interactions, the Maxwell-Boltzmann velocity distribution is violated in the quantum system. Particles that appear in quantum theory are broadly classified as fermions or bosons. In either case, particles of the same type are completely indistinguishable, and it is believed that the quantum state remains unchanged even if two particles of the same type are swapped. ... *Some of the terminology that mentions "fermion" is listed below.

…さらに,相互作用がない多粒子系でも,量子系ではマクスウェル=ボルツマンの速度分布が破れるのである。 量子論に登場する粒子は,フェルミ粒子(フェルミオンfermion)かボース粒子(ボソンboson)かに大別される。いずれの場合も同種の粒子はまったく識別不可能で,2個の同種粒子を入れ替えても量子状態は不変だと考える。… ※「fermion」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
