Lü Haoa),b), Zhu Shao-Binga),b), Qian Jun†a), Wang Yu-Zhua)
       
The momentum of the ground-state wavefunction as a function of Rydberg-dressing interaction strength ((a) and (b)) and spin polarization |〈σ z 〉| ((c) and (d)) versus nU 0 and Ω for repulsive ((a) and (c)) and attractive ((b) and (d)) cases. The parameters are Ω / E r = 2 (green solid), 4 (red dashed), and G 1 = 0.4 E r , G 2 = 0.
