标题： Fast generation of ultrastable computer glasses by minimization of an augmented potential energy

摘要： 我们提出了一种模型和协议，能够在最小计算成本的情况下生成极稳定的计算机玻璃。 该协议包括在增强的势能景观中的瞬时淬火，其中粒子半径作为额外自由度。 我们展示了在我们的方法中易于调节的玻璃的机械稳定性如何在微观和宏观可观测量中得到反映。 我们的观察表明，我们计算机玻璃的稳定性至少与由著名的Swap蒙特卡洛算法生成的计算机玻璃相当。 值得注意的是，一些关键特性在我们的方案中甚至支持定性增强的稳定性：在我们最稳定的计算机玻璃中，准局域激发的密度显示出一个间隙，其大小与粒子的多分散性成比例。 我们解释了这一观察结果，这与我们在小应力下观察到的缺乏塑性是一致的。 这也表明这些玻璃类似于实验制备的超稳定玻璃，从两能级系统中耗尽。 显示英文摘要

摘要： We present a model and protocol that enable the generation of extremely stable computer glasses at minimal computational cost. The protocol consists of an instantaneous quench in an augmented potential energy landscape, with particle radii as additional degrees of freedom. We demonstrate how our glasses' mechanical stability, which is readily tunable in our approach, is reflected both in microscopic and macroscopic observables. Our observations indicate that the stability of our computer glasses is at least comparable to that of computer glasses generated by the celebrated Swap Monte Carlo algorithm. Strikingly, some key properties support even qualitatively enhanced stability in our scheme: the density of quasilocalized excitations displays a gap in our most stable computer glasses, whose magnitude scales with the polydispersity of the particles. We explain this observation, which is consistent with the lack of plasticity we observe at small stress. It also suggests that these glasses are depleted from two-level systems, similarly to experimental vapor-deposited ultrastable glasses.
