超统计量是与具有强度变量的时空不均匀性的驱动非平衡系统相关的不同统计量的叠加(例如,逆温度)。它们包含Tsallis统计量作为特例。我们在这里开发的技术,使我们能够分析一般超统计量的平稳分布的大能量渐近。一个鞍点近似的发展,涉及到这个问题的变分原理。并给出了具体的算例。
Superstatistics are superpositions of different statistics relevant for driven nonequilibrium systems with spatiotemporal inhomogeneities of an intensive variable (e.g., the inverse temperature). They contain Tsallis statistics as a special case. We develop here a technique that allows us to analyze the large energy asymptotics of the stationary distributions of general superstatistics. A saddle-point approximation is developed which relates this problem to a variational principle. Several examples are worked out in detail.
