A phase-space representation of the Aharonov-Bohm effect is presented. It s
hows that the shift of interference fringes is associated to the interferen
ce term of the Wigner distribution function of the total wave-function, whe
reas the interference pattern is defined by the common projections of the W
igner distribution functions of the interfering beams. (C) 2001 Elsevier Sc
