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、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人，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。南安普顿部分将从实验和理论上解决冷却过程的基本方面，这些方面是由于捕获的分子与其在单一镜子中的反射相互作用延迟而产生的，以及这一原型方案的开发，该原型方案利用可以在我们的制造设施中生产的纳米结构镜像阵列，并且显示几何和等离子体共振。因此，我们的特别目标是了解和探索腔中介冷却的最基本版本，并开发适合作为未来技术的纳米级集成的新实现。

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.The Southampton component will address, both experimentally and theoretically, fundamental aspects of the cooling process that result from the retarded interaction of a trapped molecule with its reflection in a single mirror, and developments of this prototype scheme that exploit nanostructured mirror arrays that can be produced in our fabrication facilities, and which show both geometric and plasmonic resonances. Our particular aims are hence to understand and explore the most basic version of cavity-mediated cooling, and to develop new implementations suitable for nanoscale integration as a future technology.
