  We experimentally investigate the clogging and jamming of interacting
paramagnetic colloids driven through a quenched disordered landscape of fixed
obstacles. When the particles are forced to cross a single aperture between two
obstacles, we find an intermittent dynamics characterized by an exponential
distribution of burst size. At the collective level, we observe that quenched
disorder decreases the particle ow, but it also greatly enhances the "faster is
slower" effect, that occurs when increasing the particle speed. Further, we
show that clogging events may be controlled by tuning the pair interactions
between the particles during transport, such that the colloidal ow decreases
for repulsive interactions, but increases for anisotropic attraction. We
provide an experimental test-bed to investigate the crucial role of disorder on
clogging and jamming in driven microscale matter.
