Extending mode-coupling theory, we elaborate a microscopic theory for the glass transition of liquids confined between two parallel flat hard walls. The theory contains the standard mode-coupling theory equations in bulk and in two dimensions as limiting cases and requires as input solely the equilibrium density profile and the structure factors of the fluid in confinement. We evaluate the phase diagram as a function of the distance of the plates for the case of a hard sphere fluid and obtain an oscillatory behavior of the glass transition line as a result of the structural changes related to layering.
扩展模式耦合理论,我们详细阐述了一种用于描述两平行硬平板之间受限液体玻璃化转变的微观理论。该理论包含了标准的体相和二维模式耦合理论方程作为限制情况,并且仅需要作为输入的是受限流体的平衡密度分布和结构因子。我们针对硬球流体的情况评估了作为板间距函数的相图,并得到了由于与分层相关的结构变化导致玻璃化转变线呈振荡行为的结果。
