Abstract
Motivated by Open Problem 17 in Damanik-Fillman's manuscript , we study the decay rate of limit-periodic approximation such that ballistic transport persists in the limit-periodic setting. We show an exponential decay rate, roughly $\|\mathscr{J}-\mathscr{J}_{q_n}\|\sim e^{-\eta q_n}$, is sufficient. This improves on earlier results of Fillman arXiv:1603.01173
