摘要翻译：
我们用数值模拟来研究平衡状态下强烈相分离的二维粒子混合物。当系统在存在淬火无序的情况下受到外部驱动时，塑性流动以曲流和强混合通道的形式发生。在某些情况下，即使在没有热涨落的情况下，这也能产生先前分离的粒子物种的快速和完全混合，以及横向扩散的增强。我们将混合相图映射为外部驱动和猝灭无序参数的函数。

英文摘要：
We use numerical simulations to examine two-dimensional particle mixtures that strongly phase separate in equilibrium. When the system is externally driven in the presence of quenched disorder, plastic flow occurs in the form of meandering and strongly mixing channels. In some cases this can produce a fast and complete mixing of previously segregated particle species, as well as an enhancement of transverse diffusion even in the absence of thermal fluctuations. We map the mixing phase diagram as a function of external driving and quenched disorder parameters.
