    "abstract": "We study the connection between Berry phases and quantum phase transitions of\ngeneric quantum many-body systems. Consider sequences of Berry phases\nassociated to sequences of loops in the parameter space whose limit is a point.\nIf the sequence of Berry phases does not converge to zero, then the limit point\nis a quantum critical point. Quantum critical points are associated to failures\nof adiabaticity. We discuss the remarkable example of the anisotropic XY spin\nchain in a transverse magnetic field and detect the XX region of criticality.",
