(color online) Potential distribution for ⁸⁷Rb in the hyperfine states and . (a) Identical double-well potential created by static and fictitious magnetic fields: . (b) For hyperfine state , the MW repulsive potential increases the separation between the double-well OFMTs: . (c) For hyperfine state , the MW attractive potential merges the two OFMTs: .
