我们证明了在反射几何中电子自旋系综和三维腔之间的强耦合。我们还发现，在集体耦合强度g(c)小于自旋线宽gamma(s)或腔线宽的条件下，可以观察到腔/自旋谱的抗交叉。我们确定了g(c)与gamma(s)的比值(g（c)/gamma(s)>0.64）作为观察空腔频率分裂的条件。最后，我们证实了g(c)的尺度是根号N，其中N是极化自旋的个数。(C) 2011年美国物理研究所。(doi: 10.1063/1.3601930)
We demonstrate the strong coupling between an electron spin ensemble and a three-dimensional cavity in a reflection geometry. We also find that an anticrossing in the cavity/spin spectrum can be observed under conditions that the collective coupling strength g(c) is smaller than the spin linewidth gamma(s) or the cavity linewidth. We identify a ratio of g(c) to gamma(s) (g(c)/gamma(s)>0.64) as a condition to observe a splitting in the cavity frequency. Finally, we confirm that g(c) scales with root N, where N is the number of polarized spins. (C) 2011 American Institute of Physics. [doi:10.1063/1.3601930]
