Moderate Deviations for the SSEP with a Slow Bond

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 particular bond, where is $N$. Above, $N$ scaling parameter. This model has been considered in context of hydrodynamic limits, fluctuations and large deviations. investigate moderate deviations from hydrodynamics obtain deviation principle.
