涨落的系综依赖性和系综的正则/微正则等价性

Ensemble dependence of fluctuations and the canonical/micro-canonical equivalence of ensembles

Nicoletta Cancrini, Stefano Olla

摘要:

我们研究了连续系统中微正则系综和正则系综在相应Gibbs测度收敛意义下的等价性。这是通过证明一个局部中心极限定理和一个局部大偏差原理得到的。作为应用,我们证明了Lebowitz-Percus-Verlet的一个公式。它给出了一个广泛的可观察到的,如动能,在一个经典的微正则系综在固定的能量均方波动。

英文摘要:

We study the equivalence of microcanonical and canonical ensembles in continuous systems, in the sense of the convergence of the corresponding Gibbs measures. This is obtained by proving a local central limit theorem and a local large deviations principle. As an application we prove a formula due to Lebowitz-Percus-Verlet. It gives mean square fluctuations of an extensive observable, like the kinetic energy, in a classical micro canonical ensemble at fixed energy.
