论文摘要
在实验和模拟中，与玻璃形成相关的极端变慢会导致严重的困难，以准备深深的淬火，退火良好的玻璃材料。最近，提出了实现这种深淬火的方法，包括在实验侧的蒸气沉积和模拟侧的“交换蒙特卡洛”和振荡性剪切。在不同协议下产生的玻璃之间的关系尚不清楚。在这里，我们表明振荡性剪切和“交换蒙特卡洛”会导致热力学等效的眼镜在外部应变下共享相同的统计力学和相似的机械响应。
The extreme slowing down associated with glass formation in experiments and in simulations results in serious difficulties to prepare deeply quenched, well annealed, glassy material. Recently, methods to achieve such deep quenching were proposed, including vapor deposition on the experimental side and "Swap Monte Carlo" and oscillatory shearing on the simulation side. The relation between the resulting glasses under different protocols remains unclear. Here we show that oscillatory shear and "Swap Monte Carlo" result in thermodynamically equivalent glasses sharing the same statistical mechanics and similar mechanical responses under external strain.
