Abstract: On the basis of a model we capture the role of strong attractive interactionin suppressing the rotational degrees of freedom of the system and volumeexclusion in keeping microscopic symmetry-breaking intact to result insuper-diffusive transport of small systems in a thermal atmosphere over a largetime scale. Our results, characterize such systems on the basis of having asuper-diffusive intermediate regime in between a very small and large timescales of diffusive regimes. Although, the Brownian ratchet model fails toaccount for the origin of motility in actin polymerization propelleddirectional motion of bacterium like Listeria Monocytogene LM and similarbio-mimetic systems due to the presence of strong attractive forces, our modelcan account for the origin of directional transport in such systems on thebasis of the same interactions.
