摘要:

我们研究在潜在地面实验中的引力子-光子转换。对于引力子到光子的跃迁,我们计算了在球形原子电场存在下的引力子-原子相互作用截面;所得结果适用于能量约100 keV至1 GeV的引力子,并在极高频下沿相干长度得到增强;因此这提供了利用现有中微子设施捕捉来自宇宙的MeV级引力子的机会。对于光子到引力子的跃迁,我们提出使用纠缠光子对来计数穿过横向磁隧道的丢失光子的实验,这可用于验证引力场的能量量子化。

英文摘要:

We study graviton-photon conversion in potential ground-based experiments. From graviton to photon transition, we calculate the cross section of graviton-atom interaction in the presence of spherical atomic electric fields; the obtained results hold for graviton energy around 100 keV to 1 GeV, and would be enhanced along the coherent length in extremely high frequencies; thus it gives a chance to catch MeV level gravitons from the universe with current neutrino facilities. From photon to graviton transition, we propose an experiment using entangled photon pairs to count missing photons passing through transverse magnetic tunnel, which could be used to verify the energy quantization of gravitational field.
