✦ Synopsis

We study a set of nonlinear di usion equations describing the evolution of densely packed particles under gravity subject to random vibrations. Although the thermodynamics of the model predicts no phase separation at all, the dynamics displays both normal and reverse segregation depending on the mass of the species present in the system.
