论均衡中幂律的起源

On the origin of power-laws in equilibrium

Michele Campisi, Fei Zhan, Peter Hänggi

摘要:

在库仑引力场中的粒子有一个有趣的性质:它的比热是常数和负值。我们表明,无论是分析和数值,当一个经典的哈密顿系统与一个这样的负比热物体保持弱接触,其统计符合厚尾幂律分布的幂指数由$C/k_B-1$,其中$k_B$是玻耳兹曼常量和$C$是热容。

英文摘要:

A particle in the attractive Coulomb field has an interesting property: its specific heat is constant and negative. We show, both analytically and numerically, that when a classical Hamiltonian system stays in weak contact with one such negative specific heat object, its statistics conforms to a fat-tailed power-law distribution with power index given by $C/k_B-1$, where $k_B$ is Boltzmann constant and $C$ is the heat capacity.
