光学结合可以理解为分子间力的激光扰动。应用最先进的QED理论，它显示了光如何移动，扭曲和从分子和纳米粒子创建有序阵列。探索了激光强度、几何形状和偏振的依赖关系，展示了复杂的势能景观。对可用几何自由度的详细探索揭示了局部力和扭矩的意外模式。许多位置的当地潜在的最小值和最大值可以定位，并绘制在等高线图。然后确定稳定岛和其他结构。
Optical binding can be understood as a laser perturbation of intermolecular forces. Applying state-of-the-art QED theory, it is shown how light can move, twist and create ordered arrays from molecules and nanoparticles. The dependence on laser intensity, geometry and polarization are explored, and intricate potential energy landscapes are exhibited. A detailed exploration of the available degrees of geometric freedom reveals unexpected patterns of local force and torque. Numerous positions of local potential minimum and maximum can be located, and mapped on contour diagrams. Islands of stability and other structures are then identified.
