Abstract

We theoretically study physical properties of one-dimensionally and regularly placed solutes. The solute is rigid-body, has arrow-like shape, and changes its direction up or down. If the solutes are immersed in continuum solvent, nothing happens in the system. However, the property of the directions differs in granular solvent (e.g., hard-sphere solvent). Depending on distance between the nearest-neighbor solutes, the directional property periodically changes as follows: "ferromagnetic-like" \leftrightarrow "random" \leftrightarrow "antiferromagnetic-like". Furthermore, the directional property decays into "random" as the distance increases. Studying a newly created nano-system theoretically, it is able to discover a new or interesting property hiding in nano-material world. We believe that such an approach gives physics research a new direction and contributes to nanotechnology.
