论文摘要
我们使用Langevin动力学模拟来研究具有大小和能量分散性的颗粒的致密2D系统。我们比较了两种类型的bidisperse系统，这些系统在粒度和交互参数之间的相关性上有所不同：在一个系统中，大粒子具有较高的相互作用参数，而小粒子的相互作用参数较低，而在另一个系统中，情况逆转。我们研究了这两个系统的不同阶段，并将它们与具有大小但没有能量差异性的系统的阶段进行了比较。我们表明，取决于大颗粒和小颗粒之间的相互作用强度，冷却至低温会产生均匀的玻璃或镶嵌晶体。
We use Langevin dynamics simulations to study dense 2d systems of particles with both size and energy polydispersity. We compare two types of bidisperse systems which differ in the correlation between particle size and interaction parameters: in one system big particles have high interaction parameters and small particles have low interaction parameters, while in the other system the situation is reversed. We study the different phases of the two systems and compare them to those of a system with size but not energy bidispersity. We show that, depending on the strength of interaction between big and small particles, cooling to low temperatures yields either homogeneous glasses or mosaic crystals.
