Renormalization of the diffusion coefficient in a fluctuating fluid III

The previously developed theory for the renormalization of the diffusion coefficient is applied to a particle of finite size. In the zero-wavenumber, zero-frequency limit the usual Stokes-Einstein result is obtained. The frequency-dependent Burnett coefficients are discussed and it is shown that they diverge in the zero-frequency limit due to the long-time tail in the Stokes-Boussinesq drag memory kernel.
