研究了四能级原子自发辐射中的量子干涉。原子有两个上能级，它们通过相同的真空模耦合到一个公共的下能级，并被相干场驱动到一个辅助能级。干扰可以导致自发辐射谱中谱线的消除和稳态下的自发辐射抵消。
Quantum interference in spontaneous emission from a four-level atom is investigated. The atom has two upper levels coupled by the same vacuum modes to a common lower level and is driven by a coherent field to an auxiliary level. Interference can lead to the elimination of a spectral line in the spontaneous emission spectrum and spontaneous emission cancellation in steady state.
