我们从理论上研究了嵌入两个偶极耦合两能级原子并与单模光波导相互作用的混合原子光机系统中的单光子传输。这种混合系统中单光子传播的传输幅度是通过实空间方法获得的。结果表明，偶极-偶极相互作用可以显着改变单光子光谱的振幅和对称性。有趣的是，我们发现偶极-偶极相互作用与正原子-腔失谐起着相似的作用。此外，可以通过增加偶极-偶极相互作用来减弱原子耗散的影响。
We theoretically investigate the single-photon transport in a hybrid atom-optomechanical system embedded with two dipole-coupled two-level atoms, interacting with a single-mode optical waveguide. The transmission amplitudes for the single-photon propagation in such a hybrid system are obtained via a real-space approach. It is shown that the dipole–dipole interaction can significantly change the amplitudes and symmetries of the single-photon spectra. Interestingly, we find that the dipole–dipole interaction plays a similar role as does the positive atom–cavity detuning. In addition, the influence from the atomic dissipation can be weakened by increasing the dipole–dipole interaction.
