title: Segregation in granular matter under horizontal swirling excitation.
abstract: A segregation phenomenon in a horizontally vibrated monolayer of granular matter is studied experimentally. In a binary mixture of small spheres and larger disks, the collapse speed of the disks increases dramatically with increasing granular temperature. The scaling behavior can be understood by applying arguments from kinetic gas theory.
