R. K. Bhaduri, M. V. N. Murthy, Diptiman Sen

摘要:

本文考虑N个粒子在一维空间中以平方反比势相互作用(Calogero-Sutherland-Moser模型)。当被谐波捕获时,其经典的正则配分函数的排斥制度是已知的文献。我们首先提出一个简洁的重新推导这个结果。状态方程,然后计算被困和均匀的气体。最后,得到了分数不相容统计的吴分布函数的经典极限,并利用该分布函数重新推导了均匀气体的经典维里展开式.

英文摘要:

We consider N particles interacting pair-wise by an inverse square potential in one dimension (Calogero-Sutherland-Moser model). When trapped harmonically, its classical canonical partition function for the repulsive regime is known in the literature. We start by presenting a concise re-derivation of this result. The equation of state is then calculated both for the trapped and the homogeneous gas. Finally, the classical limit of Wu's distribution function for fractional exclusion statistics is obtained and we re-derive the classical virial expansion of the homogeneous gas using this distribution function.
