Cavity-mediated cooling using nanostructured surfaces

空腔介导的冷却已经成为唯一一种有可能将分子物种冷却到量子相干性和简并所需的微开尔文温度的通用技术。EuroQUAM CMMC项目将连接领先的理论家和实验家，包括该技术的发明者和实验先驱，将其发展成为一种真正实用的技术，加强欧洲在该领域的领导地位。四个主要实验将探索互补构型的光谱，空腔介导的冷却将首次应用于分子；同时，一个全面的理论方案将审查潜在的机制，并确定实现实用性的最佳途径。理论和实验之间，寻路和基础研究之间的密切联系，将使每个人都能指导和通知其他人，确保腔介导的冷却迅速发展成为量子相干分子物理和化学新领域的广泛支持技术。对于强耦合状态，已经提出了集体冷却方案。利兹大学研究的目的是为被困在高泄漏光学腔内的粒子的集体冷却发展一套详细的理论。这个所谓的坏腔体系的理论结果将与其他地方报道的尚未解释的实验研究进行比较。此外，他们将为该网络中实验组使用的物理装置的设计提供具体的输入，实验组将在所谓的坏腔限制中操作他们的腔。

Cavity-mediated cooling has emerged as the only general technique with the potential to cool molecular species down to the microkelvin temperatures needed for quantum coherence and degeneracy. The EuroQUAM CMMC project will link leading theoreticians and experimentalists, including the technique's inventors and experimental pioneers, to develop it into a truly practical technique, reinforcing European leadership in this field. Four major experiments will explore a spectrum of complementary configurations and cavity-mediated cooling will be applied to molecules for the first time; a comprehensive theoretical programme will meanwhile examine the underlying mechanisms and identify the optimal route to practicality. The close connections between theory and experiment, and between pathfinding and underpinning studies, will allow each to guide and inform the others, ensuring that cavity-mediated cooling is swiftly developed as a broad enabling technology for new realms of quantum coherent molecular physics and chemistry.Collective cooling schemes have already been proposed for the strong coupling regime. The aim of the Leeds research is to develop a detailed theory for the collective cooling of particles trapped inside a highly leaky optical cavity. The theoretical results obtained for this so-called bad-cavity regime will be compared with the still unexplained experimental studies reported elsewhere. Moreover, they will provide concrete input in the design of the physical setups used by the experimental groups in this network, who will operate their cavity in the so-called bad cavity limit.
