提出了一种将耗散粒子动力学(DPD)映射到经典分子动力学的新方法。通过引入代表原子群的不变体积元,我们表明,新兴的布朗准粒子之间的相互作用自然产生的几何定义,包括保守的排斥力和耗散阻力。准粒子,这是由原子的主机溶剂,而不是简单地沉浸在它,提供了一个原子和DPD水平之间的联系和一个实用的路线,以提取DPD参数作为直接的统计平均原子的主机系统。该方法为介观DPD提供了分子基础。它说明了简单的单原子超临界流体的例子,证明良好的协议的热力学和输运性质计算的原子系统和DPD使用所获得的参数。
We present a novel approach of mapping dissipative particle dynamics (DPD) into classical molecular dynamics. By introducing the invariant volume element representing the swarm of atoms, we show that the interactions between the emerging Brownian quasiparticles arise naturally from its geometric definition and include both conservative repulsion and dissipative drag forces. The quasiparticles, which are composed of atomistic host solvent rather than being simply immersed in it, provide a link between the atomistic and DPD levels and a practical route to extract the DPD parameters as direct statistical averages over the atomistic host system. The method thus provides the molecular foundations for the mesoscopic DPD. It is illustrated on the example of simple monatomic supercritical fluid demonstrating good agreement in thermodynamic and transport properties calculated for the atomistic system and DPD using the obtained parameters.
