In this talk,I will introduce two types of novel topological states found in two-dimensional materials:quantum spin-quantum anomalous Hall(QSQAH)and non-Dirac quantum anomalous Hall(NDQAH)states,based on density-functional theory and Wannier function methods.One new category of valley polarized topological insulators,QSQAH,where the QAH effect occurs at one valley and the quantum spin Hall(QSH)effect occurs at the other valley,is predicted in the decorated Sb(111)monolayers.
