Title: The multiscale coarse-graining method. VI. Implementation of three-body coarse-grained potentials. Author: Larini L, Lu L, Voth GA. Journal: J Chem Phys; 2010 Apr 28; 132(16):164107. PubMed ID: 20441258. Abstract: Many methodologies have been proposed to build reliable and computationally fast coarse-grained potentials. Typically, these force fields rely on the assumption that the relevant properties of the system under examination can be reproduced using a pairwise decomposition of the effective coarse-grained forces. In this work it is shown that an extension of the multiscale coarse-graining technique can be employed to parameterize a certain class of two-body and three-body force fields from atomistic configurations. The use of explicit three-body potentials greatly improves the results over the more commonly used two-body approximation. The method proposed here is applied to develop accurate one-site coarse-grained water models.[Abstract] [Full Text] [Related] [New Search]
