论量子微正则平衡

On quantum microcanonical equilibrium

Dorje C. Brody, Daniel W. Hook, Lane P. Hughston

摘要:

提出了一个量子微正则假设作为小量子系统平衡性质的基础。导出了相应的态密度的表达式,并用于建立有限量子系统的相变的存在性。引入巨微正则系综,利用它可以得到量子统计力学中新的严格结果。

英文摘要:

A quantum microcanonical postulate is proposed as a basis for the equilibrium properties of small quantum systems. Expressions for the corresponding density of states are derived, and are used to establish the existence of phase transitions for finite quantum systems. A grand microcanonical ensemble is introduced, which can be used to obtain new rigorous results in quantum statistical mechanics.
