| contents | After the introduction of sandpile model a number of different variants have been studied. In most of
these models sand particles are indistinguishable. Here we have painted the sand particles using a
few distinct colors, and restrict them to move in linear trajectories only along their assigned lattice axes,
one axis reserved for one color. Different colored particles interact among themselves through the
toppling of unstable sand columns. Consequently, the avalanches or in general the self-organization
processes in the sandpile has no overall preferred direction, though the individual particles
execute directed motion. For such non-abelian colored sandpiles the steady states are found to be
different and also the avalanche size distributions. This sandpile so defined has a non-trivial spatial
structure and belongs to a different universality class of sandpile models. Dynamics of a granular heap
with grains of different colors and properties may be described using this sandpile. |
