从理想气体到理想玻璃:随机密堆积的可逆路径

From the ideal gas to an ideal glass: reversible path to random close packing

Leslie V. Woodcock

摘要:

一个可重复的RCP状态是通过一个定义明确的速率过程,这是一阶的自由体积,从平衡热力学状态的硬球流体。RCP状态也通过热力学途径复制,该热力学途径抑制小晶体晶核的频繁产生,这可能导致紧密堆积的不均匀性。简单立方单占据(SCSO)池系统(其中结晶实际上被禁止)提供了从理想气体到理想玻璃(RCP)的一路可逆路径。通过这种途径,RCP的独特表征成为可能。

英文摘要:

A reproducible RCP state is obtained by a well-defined rate process, which is first-order in free volume, starting from an equilibrium thermodynamic state of the hard-sphere fluid. The RCP state is also reproduced by a thermodynamic pathway that inhibits the frequent production of small crystal nucleites which can lead to heterogeneities at close packing. The simple-cubic single-occupancy (SCSO) cell system, in which crystallization is de facto prohibited, provides a reversible path all the way from the ideal gas to the ideal glass (RCP). By such a route, unique characterization of RCP becomes possible.
