    "abstract": "We study the geometric phase (GP)in presence of diabolic (DP) and exceptional\n(EP) points. While the GP associated with the DP is the flux of the Dirac\nmonopole, the GP related to the EP, being complex one, is described by the flux\nof complex magnetic monopole. For open systems, in week-coupling limit, the\nleading environment-induced contribution to the real part of complex GP is\ngiven by a quadrupole term, and to its imaginary part by a dipolelike field. We\nfind that the GP has a finite gap at the DP and infinite one at the EP.",
