Simulation of Inhomogeneous Columns of Beads under Vertical Vibration

At , , and (the same as in
Figure 4) and placing 5 heavier spheres (mass ) on the bottom
and 5 spheres (mass ) on the top of
the column with mass ratio makes the
condensation and fluidization regimes to coexist (an intermediate situation
between Figures 3 and 4). The inset shows the frequency spectrum of the
center-of-mass motion.
