Abstract Let {u (t, x)} t> 0, x∈ R denote the solution to the parabolic Anderson model with initial condition δ 0 and driven by space-time white noise on R+× R, and let p t (x):=(2 π t)− 1/2 exp{− x 2/(2 t)} denote the standard Gaussian heat kernel on the line. We use a non-trivial adaptation of the methods in our companion papers [6],[7] in order to prove that the random field x↦ u (t, x)/p t (x) is ergodic for every t> 0. And we establish an associated quantitative central limit theorem following the approach based on the Malliavin-Stein method introduced in Huang, Nualart, and Viitasaari [11].
