Figure 3
The absolute phase shifts vs the scaled detuning.
The dashed and dashed-dot lines show the absolute phase shifts |θ0/π| and |θ/π| that the reflected photon gets, with the ensemble in the states 
and 
, respectively. The solid line represents the absolute value of the phase shifts difference |Δθ/π| = |θ0/π − θ/π|. The inset shows the phase shifts vs the scaled detuning. θ0/π and θ/π that the reflected photon gets, with the ensemble in 
and 
, respectively.
