全同经典粒子:半费米子和半玻色子

Identical classical particles: half fermions and half bosons

Falk Töppel, Andrea Aiello

摘要:

我们研究了自然界中已知的三种情况下的粒子不相容性问题:全同经典粒子,全同玻色子和全同费米子。利用不同类型的粒子与具有不同对称性的希尔伯特空间矢量相关联的事实,我们建立了几种不同的算符,如粒子数1和粒子间关联算符,对一对相同的(a)经典粒子,(b)玻色子和(c)费米子的状态的期望值之间的关系。我们发现一对全同经典粒子的量子行为恰好具有半费米子和半玻色子的特征。

英文摘要:

We study the problem of particle indistinguishability for the three cases known in nature: identical classical particles, identical bosons and identical fermions. By exploiting the fact that different types of particles are associated with Hilbert space vectors with different symmetries, we establish some relations between the expectation value of several different operators, as the particle number one and the interparticle correlation one, evaluated for states of a pair of identical (a) classical particles, (b) bosons and (c) fermions. We find that the quantum behavior of a pair of identical classical particles has exactly half fermionic and half bosonic characteristics.
