通过库仑力相互作用的带电系统可以有效地模拟通过引入一个局部的，扩散的自由度的电场。本文建立了与该算法相对应的连续介质电动力学方程，并研究了这些方程与移动的电荷耦合时的涨落谱。我比较了带电晶格气体的模拟计算，并研究了电荷和密度波动的动力学。该算法可以理解为以太力学模型的实现。
Charged systems interacting via Coulomb forces can be efficiently simulated by introducing a local, diffusing degree of freedom for the electric field. This paper formulates the continuum electrodynamic equations corresponding to the algorithm and studies the spectrum of fluctuations when these equations are coupled to mobile charges. I compare the calculations with simulations of a charged lattice gas, and study the dynamics of charge and density fluctuations. The algorithm can be understood as a realization of a mechanical model of the ether.
