This project will investigate the forces involved in optical tweezers used to trap, hold and manipulate microscopic particles in a non-contact manner. We will explore how to trap particles as stiffly as possible - both for spheres and for more complex shapes such as nano-probes used to measure a surface profile.We also believe this is closely linked to the question of how to control the shape of liquid droplets deformed using optical tweezers, and will explore the question of how to maximize the deforming forces on the droplet surface.This project will use mathematical and numerical techniques to explore, understand and predict these effects, and gain a better understanding of how we can control and manipulate matter on a microscopic scale. In collaboration with experimental researchers, our goal is to make testable predictions and devise new and improved methods for optimal optical trapping and manipulation.

该项目将研究用于以非接触方式捕获、固定和操纵微观颗粒的光镊所涉及的力。我们将探索如何尽可能刚性地捕获颗粒-无论是球体还是用于测量表面轮廓的纳米探针等更复杂形状的颗粒。我们还认为这与如何控制使用光镊变形的液滴形状的问题密切相关。并将探讨如何使液滴表面的变形力最大化的问题。该项目将使用数学和数值技术来探索，理解和预测这些效应，并更好地理解我们如何在微观尺度上控制和操纵物质。通过与实验研究人员的合作，我们的目标是做出可测试的预测，并设计新的和改进的方法，以实现最佳的光学捕获和操作。
