含不动粒子的粒子反应模型中的精确关联函数

Exact correlation functions in particle-reaction models with immobile particles

Christophe Chatelain, Malte Henkel, Mário J. De Oliveira, Tânia Tomé

摘要:

精确的结果,以及在两个模型中的不动粒子,包含一个单一的物种或两个不同的物种,粒子密度,并推导出。该模型通过对湮灭的下降动力学发展,其中每个粒子在其整个历史中最多相互作用一次。由此产生的大量定态导致非零构型熵。我们的结果是建立在任意初始条件下,并通过生成函数的方法。单组分模型是一维零温动力学伊辛模型与Kimball-Deker-Haake动力学的对偶。这样,无限和半无限链以及贝特格都可以被分析。讨论了二聚体和弱敲击颗粒材料的随机顺序吸附的关系。

英文摘要:

Exact results on particle-densities as well as correlators in two models of immobile particles, containing either a single species or else two distinct species, are derived. The models evolve following a descent dynamics through pair-annihilation where each particle interacts at most once throughout its entire history. The resulting large number of stationary states leads to a non-vanishing configurational entropy. Our results are established for arbitrary initial conditions and are derived via a generating-function method. The single-species model is the dual of the 1D zero-temperature kinetic Ising model with Kimball-Deker-Haake dynamics. In this way, both infinite and semi-infinite chains and also the Bethe lattice can be analysed. The relationship with the random sequential adsorption of dimers and weakly tapped granular materials is discussed.
