在 Rb Rydberg 原子的室温蒸气中，共振偶极子-偶极子能量转移通过二元碰撞发生。相比之下，在磁光陷阱产生的 300 μK 蒸气中，原子几乎被冻结在原地，许多原子同时相互作用，就像在非晶固体中一样。由于多原子同时相互作用，能量转移共振的频率显着拓宽。
In a room temperature vapor of Rb Rydberg atoms, resonant dipole-dipole energy transfer occurs via binary collisions. In contrast, in the 300 mu K vapor produced by a magneto-optical trap, the atoms are nearly frozen in place and many atoms interact simultaneously, as in an amorphous solid. As a result of the simultaneous multiple atom interactions, the energy transfer resonances are broadened substantially in frequency.
