“…Understanding the driven self-organization of fluctuating assemblies is of fundamental significance. Questions concerning the existence of extremal principles, which might minimize, or maximize, entropy production for example, 60 or the importance of system history, are fundamental. 58 Understanding them, through the examination of systems like the one described above, is essential in developing the capacity for the top-down, spontaneous self-organization of nano-machines capable of performing intricate tasks at the nanoscale.…”

Multiple scattering of light induces structured interactions, or optical binding forces, between collections of small particles. This has been extensively studied in the case of microspheres. However, binding forces are strongly shape dependent: here, we turn our attention to dielectric nanowires. Using a novel numerical model we uncover rich behavior. The extreme geometry of the nanowires produces a sequence of stationary and dynamic states. In linearly polarized light, thermally stable ladder-like structures emerge. Lower symmetry, sagittate arrangements can also arise, whose configurational asymmetry unbalances the optical forces leading to nonconservative, translational motion. Finally, the addition of circular polarization drives a variety of coordinated rotational states whose dynamics expose fundamental properties of optical spin. These results suggest that optical binding can provide an increased level of control over the positions and motions of nanoparticles, opening new possibilities for driven self-organization and heralding a new field of self-assembling optically driven micromachines.
