论文摘要
我们使用掉期Monte Carlo算法在密度下在平衡条件下分析粘性球的玻璃行为，而传统的模拟和实验无法达到平衡，超越了预测的相变和动态奇异性。我们证明了一个独特的ergodic区域的存在，该区域包括先前报道的所有不同阶段，除了具有较强粘附处的相分开区域。所有结构和动态可观察的物体在这个奇异区域内逐渐发展，物理学从较小的粘附和较大密度的众所周知的硬球行为顺利演变，到更复杂的玻璃状态，其特征是在大粘附处的松弛时间尺度和长度尺度的异常分布。
We use the swap Monte Carlo algorithm to analyse the glassy behaviour of sticky spheres in equilibrium conditions at densities where conventional simulations and experiments fail to reach equilibrium, beyond predicted phase transitions and dynamic singularities. We demonstrate the existence of a unique ergodic region comprising all the distinct phases previously reported, except for a phase-separated region at strong adhesion. All structural and dynamic observables evolve gradually within this ergodic region, the physics evolving smoothly from well-known hard sphere glassy behaviour at small adhesions and large densities, to a more complex glassy regime characterised by unusually-broad distributions of relaxation timescales and lengthscales at large adhesions.
