论文摘要
真空中冷凝物质的悬浮物可以研究其与环境极端隔离的物理特性。它还提供了一个场地，可以在量子和古典世界之间的过渡中调查具有大型系统的量子力学。在这项工作中，我们研究了一个新型的混合悬浮平台，该平台将Paul陷阱与弱但高度聚焦的激光束相结合，这种配置将深层电位与出色的限制和运动检测结合在一起。我们结合了模拟和实验，以证明这种方法将真空捕获和审讯扩展到更广泛的纳米材料（例如吸收颗粒）的潜力。我们研究了不同标本的稳定性和动力学，例如荧光介电晶体和金纳米棒，并表现出稳定的捕获到1 MBAR的压力。
The levitation of condensed matter in vacuum allows the study of its physical properties under extreme isolation from the environment. It also offers a venue to investigate quantum mechanics with large systems, at the transition between the quantum and classical worlds. In this work, we study a novel hybrid levitation platform that combines a Paul trap with a weak but highly focused laser beam, a configuration that integrates a deep potential with excellent confinement and motion detection. We combine simulations and experiments to demonstrate the potential of this approach to extend vacuum trapping and interrogation to a broader range of nanomaterials, such as absorbing particles. We study the stability and dynamics of different specimens, like fluorescent dielectric crystals and gold nanorods, and demonstrate stable trapping down to pressures of 1 mbar.
