非对易费米子气体的热力学

Thermodynamics of a non-commutative fermion gas

F G Scholtz, J Govaerts

摘要:

建立在最近的解决方案的频谱的非交换以及在两个维度上,热力学,从它计算。特别是把重点放在一个理想的费米子气体局限于这样一个好。在低密度下,热力学与交换气体相同。然而,在高密度下,由于非对易性导致的隐含排除区域,热力学强烈偏离对易气体。特别是有极端宏观状态,其特征在于面积,粒子数和角动量,对应于一个单一的微观状态,因此具有零熵。当系统的大小和排除面积是可比的,热力学量,如熵,表现出非广泛的功能。

英文摘要:

Building on the recent solution for the spectrum of the non-commutative well in two dimensions, the thermodynamics that follows from it is computed. In particular the focus is put on an ideal fermion gas confined to such a well. At low densities the thermodynamics is the same as for the commutative gas. However, at high densities the thermodynamics deviate strongly from the commutative gas due to the implied excluded area resulting from the non-commutativity. In particular there are extremal macroscopic states, characterized by area, number of particles and angular momentum, that correspond to a single microscopic state and thus have vanishing entropy. When the system size and excluded area are comparable, thermodynamic quantities, such as entropy, exhibit non-extensive features.
