Individual stable atoms and molecules are seldom found far apart unless they are gases. Most matter exists in a condensed phase whose cohesion and integrity are due to fundamental interactions among the particles. The balance between dispersion forces of attraction and short-range electron-cloud repulsions—as in the Lennard-Jones potential—supports the formation of stable equilibrium structures. Remarkably, off-resonant laser radiation can induce additional, optomechanical forces between particles. A publication by Michael Burns and his team1 verified this effect experimentally for a simple system of two identical, spherical particles.The terms ‘optical binding’and ‘optical matter,’which have recently gained currency, imply possibilities for an interplay with other interactions, such as chemical bonding. Such forces offer distinctive features that can be exploited for controlled optical manipulation of matter. 2 Progress in theory is simultaneously developing along several fronts, with many investigations using classical descriptions of the radiation field. Some studies involve the demanding experimental challenges of engaging laser light to achieve the coherent manipulation and assembly of atoms and molecules.
