Lü Haoa),b), Zhu Shao-Binga),b), Qian Jun†a), Wang Yu-Zhua)
       
Ground-state phase diagrams ((a) and (b)) and spin polarization |〈σ z 〉| ((c) and (d)) for the repulsive ((a), (c), and (e)) and attractive ((b), (d), and (f)) Rydberg-dressing interactions, respectively. The spin polarization |〈σ z 〉| ((e) and (f)) at Ω / E r = 2 (green solid), 3 (blue dashed), and 4 (red dotted). Other parameters are G 1 = 0.4 E r , G 1 = 0.1 E r , and R c = 1.6 μm.
