原子去激发释放出中微子对和光子,如果在宏观目标中通过量子相干增强,有望提供一种新的中微子物理方法。然而,同样的增强机制也可能导致QED背景过程增强的严重问题。我们表明,量子电动力学的背景可以被足够的抑制在光子晶体波导中,通过使用的空间相位,在初始相干产生的过程中,在激发的目标中的印记。
Atomic deexcitation emitting a neutrino pair and a photon is expected to provide a novel method of neutrino physics if it is enhanced by quantum coherence in a macroscopic target. However, the same enhancement mechanism may also lead to a serious problem of enhanced QED background process. We show that the QED background can be suppressed enough in the photonic crystal waveguide by using the spatial phase that is imprinted in the process of initial coherence generation in the target at excitation.
