我们得到的马尔可夫运动方程的相互作用粗粒度(CG)变量和额外的通量的多体系统。研究CG变量属于原子自由度的线性组合的特殊家庭。该马尔可夫运动方程组近似于Mori精确的非马尔可夫广义Langevin方程,且易于计算机模拟求解。方程的所有参数可以从所研究的微观系统的平衡分子动力学模拟中获得。这些参数要么等于著名的静态协方差从森的连分数或他们代表广义常摩擦矩阵。我们基于Mori连分数提出了两种不同的方法来计算这些摩擦矩阵。最后,一些参数的数值计算的特殊情况下的质量中心变量的石墨烯晶格,它被发现的CG变量与它们的额外的通量在空间上非常本地的方式相互作用。
We obtain Markovian equations of motion for a many body system of interacting coarse-grained (CG) variables and additional fluxes. The investigated CG variables belong to the special family of linear combinations of atomistic degrees of freedom. The system of Markovian equations of motion approximates Mori's exact non-Markovian generalized Langevin equation and is easy to solve by computer simulation. All parameters of the equations can be obtained from equilibrium molecular dynamics simulations of the investigated microscopic system. These parameters are either equal to the famous static covariances from Mori's continued fraction or they represent generalized constant friction matrices. We propose two different ways to compute these friction matrices based on Mori's continued fraction. Finally, some of the parameters are computed numerically for the special case of centre of mass variables in the graphene lattice and it is found that the CG variables interact with their additional fluxes in a spatially very local way.
