Abstract: We prove density and current fluctuations for two examples of symmetric,interacting particle systems with anomalous diffusive behavior: the zero-rangeprocess with long jumps and the zero-range process with degenerated bonddisorder. As an application, we obtain subdiffusive behavior of a taggedparticle in a simple exclusion process with variable diffusion coefficient.
