  It is observed that strings in AdS_5 x S^5 and membranes in AdS_7 x S^4
exhibit long range phase interactions. Two well separated membranes dragged
around one another in AdS acquire phases of 2\pi/N. The same phases are
acquired by a well separated F and D string dragged around one another. The
phases are shown to correspond to both the standard and a novel type of
Aharonov-Bohm effect in the dual field theory.
