论文摘要
来自激光束的轨道角动量（OAM）可以连贯地转移到$ \ hbar $的量化单元中的环陷阱中的Bose-Einstein冷凝物中。光 - 耦合允许在离散OAM状态之间的原子的超级传递。调谐环参数和泵光的绕组数，特定的角动量状态可以被填充。反过来，这允许控制发射的光线与泵的光线不同，因为原子环将其在散射光中的贡献贴上了贡献。
The orbital angular momentum (OAM) from a laser beam can be coherently transferred to a Bose-Einstein condensate in a ring trap, in quantized units of $\hbar$. The light-matter coupling allows for the superradiant transfer of the atoms between the discrete OAM states. Tuning the ring parameters and winding number of the pump light, specific angular momentum states can be populated. This in turn allows control of the emission to generate light with OAM different from that of the pump, as the atomic ring imprints its contribution on the scattered light.
