摘要：
Recently, chiral anomaly and Berry's phase are often mentioned in the study of chiral properties of condensed matter and nuclear physics. In my talk I first give an introduction to chiral anomaly and then Berry’s phase following the original idea of Berry and Simon. The topology of Berry’s phase arises from the singularity associated with the level crossing phenomenon. This definition covers most of the popular examples of Berry's phase, but part of the freedom of the ``monopole'' associated with Berry's adiabatic phase is frozen compared to the conventional monopole. We thus suggest a term ``adiabatic monopole''.  A well-defined monopole is not derived from an adiabatic monopole. Because of this limitation, it is shown that Berry’s phase and chiral anomaly are very different, despite some recent discussions in the literature on the possible connection of these two notions.
