    "abstract": "Physical mechanism for the geometric phase in terms of angular momentum\nexchange is elucidated. It is argued that the geometric phase arising out of\nthe cyclic changes in the tranverse mode space of the Gaussian light beams is a\nmanifestation of the cycles in the momentum space of the light. Nonconservation\nof angular momentum in the spontaneous parametric down-conversion for the\nclassical light beams is proposed to be related with the geometric phase.",
