单独的稳定原子和分子很少相距很远,除非它们是气体。大多数物质以凝聚态存在,凝聚力和完整性源于粒子之间的基本相互作用。色散引力和短程电子云斥力之间的平衡--如在Lennard-Jones势中--支持稳定平衡结构的形成。值得注意的是,非共振激光辐射可以在粒子之间诱导额外的光机械力。迈克尔·伯恩斯和他的团队1在一篇论文中对两个完全相同的球形粒子组成的简单系统进行了实验验证。最近流行起来的术语“光学结合”和“光学物质”暗示了与其他相互作用相互作用的可能性,比如化学键。这种力提供了独特的特征,可以用来对物质进行受控的光学操纵。2理论上的进展同时沿着几条战线发展,许多研究都使用了辐射场的经典描述。一些研究涉及使用激光来实现原子和分子的相干操纵和组装的苛刻实验挑战。
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.
