Cavity-mediated cooling using nanostructured surfaces

空穴介导的冷却已经成为唯一有可能将分子物种冷却到量子相干和简并所需的微开尔文温度的通用技术。EuroQUAM CMMC项目将把领先的理论家和实验者联系起来，包括该技术的发明者和实验先驱，将其开发成一项真正实用的技术，加强欧洲在该领域的领先地位。四个主要实验将探索互补构型的光谱，并将首次将腔中介冷却应用于分子；同时，一个全面的理论计划将检查潜在的机制，并确定通向实用的最佳途径。理论和实验之间以及探路和基础研究之间的密切联系将允许彼此指导和告知其他研究，确保腔中介冷却迅速发展为量子相干分子物理和化学新领域的广泛使能技术。针对强耦合区域的集体冷却方案已经被提出。利兹研究的目的是开发一种详细的理论，用于对困在高度泄漏的光学腔中的粒子进行集体冷却。对于这种所谓的坏腔区域所获得的理论结果，将与其他地方报道的仍未得到解释的实验研究进行比较。此外，他们将在这个网络中的实验小组使用的物理设置的设计中提供具体的输入，这些小组将在所谓的坏腔限制下操作他们的腔。

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.
