ERA NanoSci - Nanofibre Optical Interfaces for Ions, Atoms and Molecules

我们的目标是使用光学纳米纤维和光连接、操纵和控制纳米粒子。这种纳米纤维将集成到新的环境中，包括离子阱、冷原子阱和光学镊子。我们将通过实验研究单个或几个离子与光学纳米纤维的倏逝场的耦合，并探索在倏逝场附近捕获离子的可能性。在理论方面，通过倏逝场捕获纳米纤维附近的离子或原子的集体耦合将被建模。此外，利用高阶光学模式，我们的目标是定制倏逝场，并研究纳米纤维附近复杂的胶体粒子三维阵列的光学结合及其对角动量转移的响应。最后，我们将考虑在具有复杂极化模式的引导纳米纤维模式的倏逝场中捕获中性原子的可行性。

We aim to use optical nanofibres for interfacing, manipulating, and controlling nano-particles with light. Such nanofibres will be integrated into novel environments, including ion traps, cold atom traps, and optical tweezers. We will experimentally investigate the coupling of a single or few ions with the evanescent field of an optical nanofibre and explore the possibility to trap ions in the vicinity of the evanescent field. On the theory side, the collective coupling of ions or atoms trapped close to a nanofibre via evanescent fields will be modelled. Furthermore, using higher order optical modes, we aim to tailor the evanescent field and to study the optical binding of complex three dimensional arrays of colloidal particles in the vicinity of the nanofibre as well as their response to transfer of angular momentum. Finally, we will consider the feasibility of trapping neutral atoms in the evanescent field of a guided nanofibre mode exhibiting a complex polarisation pattern.
