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.

Ultracold Polar分子为量子科学实验提供了一个令人兴奋的新平台，尤其与量子多体物理学的研究有关。该博士学位项目将使用最先进的技术来产生密集的，受控的超低分子云。从构建CAF分子的缓冲气束开始，分子将通过激光放慢速度减速，然后将其捕获在磁光陷阱中。然后，分子将通过微波脉冲将其转移到单个内部量子状态。此时，将使用谐波磁陷阱中的新技术压缩云。该项目将设计为可远程控制，从而允许对分子的捕获和冷却实施远程优化过程。
