Cavity mediated cooling using nanostructured

项目摘要

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.

腔介导冷却已经成为唯一的通用技术，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。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，将其发展成为真正实用的技术，加强欧洲在该领域的领导地位。四个主要的实验将探索一系列互补的构型，腔介导的冷却将首次应用于分子;同时，一个全面的理论计划将研究潜在的机制，并确定实用的最佳途径。理论和实验之间的紧密联系，以及探索和基础研究之间的紧密联系，将使每个人都能指导和告知其他人，确保腔介导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使能技术。利兹研究的目的是为被困在高度泄漏的光学腔中的粒子的集体冷却发展一个详细的理论。我们将把这种所谓的坏腔机制的理论结果与其他地方报道的仍然无法解释的实验研究进行比较。此外，他们将在该网络中实验组使用的物理设置的设计中提供具体的输入，这些实验组将在所谓的坏腔极限中操作他们的腔。
