摘要翻译:
建立了剪切致密颗粒液体在干扰转捩附近的模耦合理论(MCT)。从颗粒的Liouville方程出发,借助投影算子技术导出了广义Langevin方程。由广义朗之万方程得到的密度相关函数的MCT方程与弹性颗粒在剪切作用下的MCT方程几乎等价。发现密度相关函数中应该存在平台。

英文摘要:
Mode-coupling theory (MCT) of sheared dense granular liquids %in the vicinity of jamming transition is formulated. Starting from the Liouville equation of granular particles, the generalized Langevin equation is derived with the aid of the projection operator technique. The MCT equation for the density correlation function obtained from the generalized Langevin equation is almost equivalent to MCT equation for elastic particles under the shear. It is found that there should be the plateau in the density correlation function.
