论文摘要
通过库仑电势相互作用的颗粒系统的密度矩阵是在kelbg的原始作品几乎完全的原始工作之后以高温极限获得的。为此，以扰动理论的第一顺序解决了blöch方程。我们试图解释派生中的所有转换，以简化对这种非平凡理论的理解。 Kelbg的溶液被广泛用于库仑系统的路径积分模拟中。
The density matrix for a system of particles interacting via the Coulomb potential is obtained in the high--temperature limit following almost entirely the original work by Kelbg. For this purpose the Blöch equation is solved in the first order of perturbation theory. We tried to explain all the transformations in the derivation in order to simplify the understanding of this non-trivial theory. The solution of Kelbg is widely used in path integral simulations of Coulomb systems.
