http://info.phys.tsinghua.edu.cn/coldquantum/spinor.html WebMost Dicke states produced so far are limited to pseudospin-1/2 (two-level) particles. In this work, we deterministically generate balanced spin-1 Dicke states in the close vicinity of l=N,m=0〉 with N~11700, by driving a spin-1 condensate through a quantum phase transition. The prepared states are characterized to exhibit a collective spin ...

"WebAbstract: In 1954, Dicke predicted that a system of quantum emitters confined to a subwavelength volume would produce a superradiant burst. For such a burst to occur, the emitters must be in the special Dicke state with zero dipole moment. We show that a superradiant burst may also arise for non-Dicke initial states with a nonzero dipole … " - Dicke states是什么
