The aim of this project is to investigate optical forces, induced by anevanescent field. Studies will be carried out using the Lateral Molecular ForceMicroscope which is a type of a SPM that uses frustrated total internal reflectionas a detection method. First part of the project will concentrate on the finalstages of the development of a new microscope as well as its subsequentcharacterisation and calibration. The new microscope will allow for moreprecise measurements of forces such as the recently observed, chiralitydependent, Belinfante's spin momentum. One of the main points of interest willbe investigations of the optically induced interactions between the probe andthe surface and how it varies depending on the type of materials of both theprobe and the surface.

这个项目的目的是研究由倏逝场引起的光力。研究将使用侧向分子力显微镜进行，这是一种SPM，使用受挫全内反射作为检测方法。该项目的第一部分将集中在新显微镜开发的最后阶段，以及随后的表征和校准。新的显微镜将允许对力进行更精确的测量，比如最近观察到的依赖于手性的贝林凡特自旋动量。主要的兴趣点之一将是研究探针和表面之间的光诱导相互作用，以及它如何根据探针和表面的材料类型而变化。
