Webb22 maj 2024 · In experiments, we prepare the initial state of the spinor BEC in a nearly AFM state by shining a π/2-pulse radio frequency radiation to the BEC on the ∣ mF = 0 level. We then shine a resonant microwave pulse with a frequency of 1.7716264 GHz on the atoms for 300 ms to remove the remaining atoms on the ∣ mF = 0 level to obtain an AFM state.
