Confinement of surface spinners in liquid metamaterials

Gorce, Jean-Baptiste; Xia, Hua; Francois, Nicolas; Punzmann, Horst; Falkovich, Gregory; Shats, Michael


We show that rotating particles at the liquid-gas interface can be efficiently manipulated using the surface-wave analogue of optical lattices. Two orthogonal standing waves generate surface flows of counter-rotating half-wavelength unit cells, the liquid interface metamaterial, whose geometry is controlled by the wave phase shift. Here we demonstrate that by placing active magnetic spinners inside such metamaterials, one makes a powerful tool which allows manipulation and self-assembly of...[Show more]
