title: Horizontal segregation in a vertically vibrated binary granular system.
abstract: We present numerical simulations and experiments on the horizontal transport and segregation of binary granular mixtures with different sizes and/or different densities in a vertically vibrated container with a sawtooth-shaped base. The larger particles migrate to the positive or negative end of the container, depending on the ratios of the diameters and the densities of two kinds of particles, the vibrating frequencies, and the accelerations. In particular, horizontal segregation occurred even if all the particles have the same size but different densities.
