将软球的玻璃态动力学映射到硬球行为

Mapping the glassy dynamics of soft spheres onto hard-sphere behavior

Michael Schmiedeberg, Thomas K. Haxton, Sidney R. Nagel, Andrea J. Liu

摘要:

我们表明,纯排斥相互作用的软球系统的动力学可以通过引入一个有效的硬球直径使用安德森周钱德勒近似确定。我们发现,这种近似,已知的描述静态性质的液体,也给出了一个很好的描述的动态量,松弛时间,甚至在附近的玻璃化转变。

英文摘要:

We show that the dynamics of soft-sphere systems with purely repulsive interactions can be described by introducing an effective hard-sphere diameter determined using the Andersen-Weeks-Chandler approximation. We find that this approximation, known to describe static properties of liquids, also gives a good description of a dynamical quantity, the relaxation time, even in the vicinity of the glass transition.
