We report new results about the two-time dynamics of an anomalously diffusing classical particle, as described by the generalized Langevin equation with a frequency-dependent noise and the associated friction. The noise is defined by its spectral density proportional to ω δ−1 at low frequencies, with 0 < δ < 1 (subdif-fusion) or 1 < δ < 2 (superdiffusion… CONTINUE READING
