最近的工作已经证明了在由短程排斥驱动的玻璃化转变和由短程吸引控制的玻璃化转变附近的动力学之间存在着强烈的定性差异。在这里，我们详细研究了非线性，高阶相关函数的行为，这些函数测量了两种类型系统中与动力异质性相关的长度尺度的增长。我们发现，在排斥和吸引情况下，这个测度在标准非线性四点动力磁化率的波矢依赖性和时间依赖性方面有质的不同。我们讨论了这些结果对于一般理解玻璃形成液体中的动力不均匀性的意义。

英文摘要：
Recent work has demonstrated the strong qualitative differences between the dynamics near a glass transition driven by short-ranged repulsion and one governed by short-ranged attraction. Here, we study in detail the behavior of non-linear, higher-order correlation functions that measure the growth of length scales associated with dynamical heterogeneity in both types of systems. We find that this measure is qualitatively different in the repulsive and attractive cases with regards to the wave vector dependence as well as the time dependence of the standard non-linear four-point dynamical susceptibility. We discuss the implications of these results for the general understanding of dynamical heterogeneity in glass-forming liquids.
