Abstract

We formulate and apply a non-replica equilibrium theory for the fluid-glass transition, glass thermodynamic properties, and jamming of hard spheres in three and all higher spatial dimensions. Numerical predictions for the zero complexity glass transition and jamming packing fractions, and a "densest" equilibrium glass, are made. The equilibrium glass equation of state is regarded as the practical continuation of its fluid analog up to jamming. The analysis provides a possible resolution to the inability of any fluid virial series re-summation based equation of state to capture jamming at a reasonable volume fraction. The numerical results are quantitatively compared with various simulation data for equilibrium hard sphere glasses in 3 to 12 dimensions. Although there are uncertainties in this comparison, the predicted zero complexity or configurational entropy and corresponding jamming packing fractions do agree well with two characteristic packing fractions deduced from the dynamic simulation data. The similarities and differences of our approach compared to the replica approach are discussed. The high dimensional scaling of the equilibrium glass transition and jamming volume fractions are also derived. The developments in this paper serve as input to Paper II [R. Jadrich and K. S. Schweizer, J. Chem. Phys. 139, 054502 (2013)] that constructs a self-consistent integral equation theory of the 3-dimensional hard sphere pair structure, in real and Fourier space, in the metastable regime up to jamming. The latter is employed as input to a microscopic dynamical theory of single particle activated barrier hopping.

摘要

我们制定并应用了一种非复制平衡理论,用于研究流体-玻璃转变、玻璃热力学性质以及在三维和更高维空间中的硬球的堵塞现象。我们对零复杂度玻璃转变和堵塞堆积分数,以及“最密集”平衡玻璃进行了数值预测。平衡玻璃状态方程被视为其流体类似物在堵塞点的实际延续。该分析为任何基于流体 virial 级数重求和的状态方程无法在合理的体积分数下捕捉堵塞现象提供了一种可能的解决方案。数值结果与 3 到 12 维平衡硬球玻璃的各种模拟数据进行了定量比较。尽管这种比较存在不确定性,但预测的零复杂度或构型熵以及相应的堵塞堆积分数与从动力学模拟数据推导出的两个特征堆积分数非常吻合。我们的方法与复制方法的异同点进行了讨论。还推导出了平衡玻璃转变和堵塞体积分数的高维标度。本文的发展为 Paper II [R. Jadrich 和 K. S. Schweizer, J. Chem. Phys. 139, 054502 (2013)]提供了输入,后者构建了 3 维硬球对结构的自洽积分方程理论,包括实空间和傅立叶空间中的亚稳区到堵塞区。后者被用作单粒子激活势垒跳跃的微观动力学理论的输入。
