We show for a large class of random Schrödinger operators Hο on \(\) and on \(\) that dynamical localization holds, i.e. that, with probability one, for a suitable energy interval I and for q a positive real,
Here ψ is a function of sufficiently rapid decrease, \(\) and PI(Hο) is the spectral projector of Hο corresponding to the interval I. The result is obtained through the control of the decay of the eigenfunctions of Hο and covers, in the discrete case, the Anderson tight-binding model with Bernoulli potential (dimension ν = 1) or singular potential (ν > 1), and in the continuous case Anderson as well as random Landau Hamiltonians.
