    "abstract": "A theoretical analysis of Pancharatnam and Berry phases is made for biphoton\nthree-level systems, which are produced via frequency degenerate co-linear\nspontaneous parametric down conversion (SPDC). The general theory of\nPancharatnam phases is discussed with a special emphasis on geodesic \u0027curves\u0027in\nHilbert space. Explicit expressions for Pancharatnam, dynamical and geometrical\nphases are derived for the transformations produced by linear phase-converters.\nThe problem of gauge invariance is treated along all the article.",
