当单个分束器接收到福克态（极低温度下的玻色-爱因斯坦凝聚体）描述的两束玻色子时，对于更多数量的粒子，会发生双光子红-欧-曼德尔效应的有趣概括。分束器后面的两个探测器处的粒子分布可以理解为两种效应综合作用的结果，即量子测量期间出现的自发相和量子角。后者引入了量子“群体振荡”，它可以被视为广义的红欧曼德尔效应，尽管它们并不总是对应于奇偶振荡。
When a single beam-splitter receives two beams of bosons described by Fock states (Bose-Einstein condensates at very low temperatures), interesting generalizations of the two-photon Hong-Ou-Mandel effect take place for larger number of particles. The distributions of particles at two detectors behind the beam splitter can be understood as resulting from the combination of two effects, the spontaneous phase appearing during quantum measurement, and the quantum angle. The latter introduces quantum “population oscillations”, which can be seen as a generalized Hong-Ou-Mandel effect, although they do not always correspond to even-odd oscillations.
