Abstract

We consider the realization of rotation of particles with a photoinduced dipole moment in the absence of an external field source. The effects considered here are based on the mechanism of the orientational interaction of at least a pair of particles that are photodipoles. We consider examples of realization of this mechanism including the geometry corresponding to the Quincke photorotation. From the point of view of applications, the variety of self-rotation in the case of a single photodipole located on or near a metal surface can be of interest. The torque for spherical particles with a radius of 10 μm is estimated.

具有光感应电偶极矩的粒子自转

摘要

我们考虑在没有外部场源的情况下利用光致偶极矩实现粒子旋转的实现。这里考虑的效果是基于至少一对作为光电偶极子的粒子的定向相互作用的机理。我们考虑这种机制的实现示例，包括与Quincke光旋转相对应的几何形状。从应用的角度来看，在单个光电偶极子位于金属表面上或附近的情况下，自旋转的变化可能是令人感兴趣的。估计半径为10μm的球形颗粒的扭矩。
