离散单体谱中的微观包含统计

Microscopic inclusion statistics in a discrete 1-body spectrum

Stephane Ouvry, Alexios P. Polychronakos

AI总结:

该研究提出微观包含统计(与排斥统计相对、粒子聚结性强于普通玻色子),推导单量子体态占据多重度的团簇乘积形式,并将其应用于一维谐振势粒子气体,得到具有特殊物理性质的类Calogero多体包含谱。

摘要:

我们提出了包含统计的微观表述,它是与排斥统计相对的概念,其中粒子的聚结倾向比普通玻色子更强。我们推导了单量子体态的微观占据多重度,证明其可分解为相邻占据态构成的团簇的乘积,且这些团簇具有增强的统计权重。将该统计应用于谐振势阱中的一维粒子气体,可得到具有有趣物理性质的类Calogero多体包含谱。

英文摘要:

We present the microscopic formulation of inclusion statistics, a counterpoint to exclusion statistics in which particles tend to coalesce more than ordinary bosons. We derive the microscopic occupation multiplicities of 1-body quantum states and show that they factorize into a product of clusters of neighbouring occupied states with enhanced statistical weights. Applying this statistics to a one-dimensional gas of particles in a harmonic well leads to a Calogero-like n-body inclusion spectrum with interesting physical properties.
