Moderate Deviations for the SSEP with a Slow Bond
Abstract
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.
