The clustering behavior of a mono-disperse granular gas is experimentally studied in an
asymmetric two-compartment setup. Unlike the random clustering in either compartment in
the case of symmetric configuration when lowering the shaking strength to below a critical
value, the directed clustering is observed, which corresponds to an imperfect pitchfork
bifurcation. Numerical solutions of the flux equation using a modified simple flux function
show qualitative agreements with the experimental results. The potential application of this …
