Investigations of fundamental optical forces in near field

本项目的目的是研究由衰减场诱导的光学力。研究将使用横向分子力显微镜进行，这是一种使用受挫全内反射作为检测方法的扫描探针显微镜。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。新的显微镜将允许更精确地测量作用力，例如最近观察到的与手性有关的贝尔芬特自旋动量。主要的兴趣之一将是研究探头和表面之间的光学诱导相互作用，以及它如何随探头和表面的材料类型而变化。

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.
