Quadratic band crossing points (QBCPs) and quantum anomalous Hall effect (QAHE) have attracted attentions of both theoretical and experimental researchers in recent years. Based on first principles calculations, we find that FeB2 monolayer is a nonmagnetic semimetal with QBCPs at K. Through symmetry analysis and k ·p invariant theory, we explain the origin of QBCPs and the associated Berry phase of 2π. Once introducing interactions, we find that there is a spontaneoustime-reversal-breaking…
