We revisit the proof of Landau damping near stable homogenous equilibria ofVlasov-Poisson systems with screened interactions in the whole space$\mathbb{R}^d$ (for $d\geq3$) that was first established by Bedrossian,Masmoudi and Mouhot. Our proof follows a Lagrangian approach and relies onprecise pointwise in time dispersive estimates in the physical space for thelinearized problem that should be of independent interest. This allows to cutdown the smoothness of the initial data required in Bedrossian at al. (roughly,we only need Lipschitz regularity). Moreover, the time decay estimates we proveare essentially sharp, being the same as those for free transport, up to alogarithmic correction.
