摘要翻译:
利用分子动力学模拟和积分方程,研究了通过连续的核软化斜坡状粒子间势相互作用的粒子系统的结构、热力学和动力学。我们发现了与在水中发现的相似的密度、动力和结构异常。对几种温度在固定密度下的径向分布函数的分析表明,这种模式可能与密度异常的起源有关。

英文摘要:
Using molecular dynamics simulations and integral equations we investigate the structure, the thermodynamics and the dynamics of a system of particles interacting through a continuous core- softened ramp-like interparticle potential. We found density, dynamic and structural anomalies similar to that found in water. Analysis of the radial distribution function for several temperatures at fixed densities show a pattern that may be related to the origin of density anomaly.
