摘要:

研究了冷$^{87}$ Rb气体5s $\rightarrow$ 5 p $\rightarrow$ 46 s梯形系统的电磁感应透明(EIT).我们发现46 s和45 p态之间的共振微波耦合导致EIT共振的Autler-Townes分裂。这种分裂可以用来通过$\pm 10^5$改变群指数,从而允许独立控制暗态极化激元的传播。我们还表明,微波敷料导致增强的相互作用的影响。特别是,我们提出了一个$1/R^3$能量之间的里德堡态共振耦合的微波场和随之而来的故障的成对相互作用近似的转移的证据。

英文摘要:

We study electromagnetically induced transparency (EIT) in the 5s$\rightarrow$5p$\rightarrow$46s ladder system of a cold $^{87}$Rb gas. We show that the resonant microwave coupling between the 46s and 45p states leads to an Autler-Townes splitting of the EIT resonance. This splitting can be employed to vary the group index by $\pm 10^5$ allowing independent control of the propagation of dark state polaritons. We also demonstrate that microwave dressing leads to enhanced interaction effects. In particular, we present evidence for a $1/R^3$ energy shift between Rydberg states resonantly coupled by the microwave field and the ensuing breakdown of the pair-wise interaction approximation.
