摘要

中子窃窃廊态是一种受离心力和物质势约束的材料表面的量子态。对这种量子态的精确测量使得在非惯性坐标系下进行量子力学测试、表征表面电位以及在纳米尺度上寻找假设的短程相互作用成为可能。利用脉冲冷中子束在SiO2凹面镜上观察了中子窃窃廊态。离心加速度a≈7×107 m/s2的测量结果与理论计算结果在1.9%范围内一致，这是由于凹镜边缘形状与理想形状的未建模偏差造成的。我们发现灵敏度本身为1×10−4，比上述协议好两个数量级。2025年由美国物理学会出版

Measurement of neutron whispering gallery states using a pulsed neutron beam

A neutron whispering gallery state is a quantum state localized on a material surface bound by the centrifugal force and the material potential. Precise measurements of such quantum states enable tests of quantum mechanics in noninertial frames, characterization of the surface potential, and searches for hypothetical short-range interactions at the nanometer scale. We observed a neutron whispering gallery state on a SiO2 concave mirror using a pulsed cold neutron beam. The measured results agree with theoretical calculations within 1.9% for the centrifugal acceleration a≈7×107 m/s2, which is due to unmodeled deviations of the shape of the concave mirror edge from an ideal one. We found that the sensitivity itself was 1×10−4, which is two orders of magnitude better than the above agreement.
