极性分子超辐射振动光谱
Vibrational spectroscopy of polar molecules with superradiance
摘要：
本文研究了在高光学深度（OD）样品中极性分子光谱中振动跃迁的合作现象和超辐射。这种协同性来自于通过偶极-偶极相互作用建立的粒子间相干性，并导致衰变过程的加速。我们将我们的计算与最近的工作进行比较[Deiglmayr等人，EUR. J. D 65，99（2011）]，并且发现非常好的一致性，这表明超辐射效应需要包括在各种各样的超冷分子设置中，包括振动和旋转状态。
英文摘要：
We investigate cooperative phenomena and superradiance for vibrational transitions in polar molecule spectroscopy when a high optical-depth (OD) sample is studied. Such cooperativity comes from the build-up of inter-particle coherence through dipole-dipole interactions and leads to the speed-up of decay process. We compare our calculation to recent work [Deiglmayr et al., Eur. Phys. J. D 65, 99 (2011)] and find very good agreement, suggesting that superradiant effects need to be included in a wide variety of ultracold molecule setups including vibrational and rotational states.
