We consider the one dimensional symmetric simple exclusion process with a slow bond. In this model, particles cross each bond at rate \(N^2\), except one particular bond, the slow bond, where the rate is N. Above, N is the scaling parameter. This model has been considered in the context of hydrodynamic limits, fluctuations and large deviations. We investigate moderate deviations from hydrodynamics and obtain a moderate deviation principle.

慢速粘结SSEP的适度偏差

我们考虑具有慢键的一维对称简单排除过程。在此模型中，颗粒在交叉速率每个键\（N ^ 2 \） ，除了一个特定键，慢键，其中所述速率是Ñ。上面的N是缩放参数。在水动力极限，波动和大偏差的背景下考虑了该模型。我们研究了与流体动力学有关的中度偏差，并获得了中度偏差原理。
