Optimised laser cooling of CaF molecules

超冷极性分子为量子科学实验提供了一个令人兴奋的新平台，特别是与量子多体物理的研究相关。这个博士项目将使用最先进的技术来产生密集的、受控的超冷分子云。从构建一个由CaF分子组成的缓冲气体束开始，这些分子将通过激光减速，然后被困在磁光阱中。然后，这些分子将通过微波脉冲转移到一个单一的内部量子态。在这一点上，云将被压缩使用一种新的技术在一个谐波磁阱。该项目将被设计为远程控制，允许对分子的捕获和冷却实施远程优化程序。

Ultracold polar molecules offer an exciting new platform for quantum science experiments, particularly relevant for studies of quantum many-body physics. This PhD project will use of a state-of-the-art techniques to produce a dense, controlled cloud of ultracold molecules. Starting with the construction of a buffer gas beam of CaF molecules, the molecules will be decelerated via laser slowing before being trapped in a magneto-optical trap. The molecules will then be transferred, via microwave pulses, into a single internal quantum state. At this point the cloud will be compressed using a new technique within a harmonic magnetic trap. The project will be designed to be remotely controllable, allowing for implementation of remote optimisation procedures for both the capturing and the cooling of the molecules.
