    • All prefactors are omitted for simplicity. Especially, we do not distinguish between the self-diffusion of the test particle and the collective diffusion of the field which may be characterized by rather different diffusion constants.

    • N holds as long as a large friction constant is used for the Langevin thermostat (Ref.). Much stronger and non-local dynamical correlations are revealed, however, for → 0. These numerical results will be discussed elsewhere together with a broader theoretical analysis which contains the mechanism presented in this paper as a special limit.
