We consider the 2D Landau Hamiltonian H perturbed by a random alloy-type potential, and investigate the Lifshitz tails, i.e. the asymptotic behavior of the corresponding integrated density of states (IDS) near the edges in the spectrum of H. If a given edge coincides with a Landau level, we obtai...

Mathematical models for sedimentation processes are needed in numerous industrial applications for the description, simulation, design and control of solid-liquid separation processes of suspensions. The first simple but complete model describing the settling of a monodisperse suspension of small...
