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