Alessandro Pesci, Pierbiagio Pieri

AI总结:

本文提出用单个离域质量与谐波束缚检验质量耦合来检验引力量子本质的新方案,并设计利用卡西米尔-波尔德力以提高实验可行性。

摘要:

现有的大多数关于引力量子本质的实验室检验方案,都基于使用两个离域质量或谐波束缚质量,并将它们制备在空间延展足够大的纯量子态中。本文提出一种基于单个离域质量的装置,该质量与一个谐波束缚的检验质量耦合,检验质量在引力作用下运动,先经历膨胀再经历压缩。我们研究了这类实验在原理上的可行性,结果表明其关键取决于能否驯服卡西米尔-波尔德力。因此,我们进一步提出一种旨在实现这一目标的设计,同时尝试利用这些力,而不仅仅是对抗它们。

英文摘要:

Most of the existing proposals for laboratory tests of a quantum nature of gravity are based on the use of two delocalized masses or harmonically bound masses prepared in pure quantum states with large enough spatial extent. Here a setup is proposed that is based on a single delocalized mass coupled to a harmonically trapped test mass (undergoing first expansion and then compression) that moves under the action of gravity. We investigate the in-principle feasibility of such an experiment, which turns out to crucially depend on the ability to tame Casimir-Polder forces. We thus proceed with a design aimed at achieving this, trying at the same time to take advantage of these forces rather than only fighting them.
