论文摘要
我们研究由与物质耦合的大规模标量场介导的经典对象之间的量子力。此类领域的存在是由暗物质，暗能量以及超出标准模型超出标准模型的隐藏部门的可能性的动机。我们在标量的存在下介绍了任意（刚性或可变形）的经典体感觉的量子工作，并证明它在需要物质保护时是有限的。例如，我们明确地表明，迪金莱特球体内的量子压力是有限的 - 可达到可重新分布的分歧。在体内，标量获得了有效的质量，从而导致量子力的行为，在刚体的情况下，这让人联想到Casimir和Casimir-Polder力之间的过渡。使用此方法，我们以简单平面几何形状计算标量诱导的量子力。在平面点的几何形状中，我们显示了如何计算量子力对原子干涉仪中可观察到的相位移位的贡献。我们表明，如果干涉仪的长度低于10 cm，则原子干涉测量法可能会成为双重耦合的光颗粒的竞争搜索方法。
We study the quantum force between classical objects mediated by massive scalar fields bilinearly coupled to matter. The existence of such fields is motivated by dark matter, dark energy, and by the possibility of a hidden sector beyond the Standard Model. We introduce the quantum work felt by an arbitrary (either rigid or deformable) classical body in the presence of the scalar and show that it is finite upon requiring conservation of matter. As an example, we explicitly show that the quantum pressure inside a Dirichlet sphere is finite -- up to renormalizable divergences. Inside the bodies the scalar acquires an effective mass, leading to a behaviour for the quantum force which, in the case of rigid bodies, is reminiscent of the transition between the Casimir and Casimir-Polder forces. With this method we compute the scalar-induced quantum force in simple planar geometries. In plane-point geometry we show how to compute the contribution of the quantum force to the phase shift observable in atom interferometers. We show that atom interferometry is likely to become a competitive search method for light particles bilinearly coupled to matter, provided that the interferometer arms have lengths below ~10 cm.
