Topological materials have been attracting great attention since the discovery of graphene. The concept of topological materials itself gets expanded as well. Up to now, various topological materials were proposed and many of them were verified by experiment. This inspired us to explore novel topological phase and their material realizations in 2D and 3D crystals. In this talk, I will introduce some of my theoretical work related to novel topological phase and materials. I mainly address on my talk on two aspects, one is 2D double Weyl fermions and pseudospin-1 fermions found in blue phosphorene oxide and Mg2C monolayer; the second is the Hourglass Dirac chain phase and its material realization in ReO2. Hopefully, these results will be helpful for advancing our understanding of topological materials and for designing new functional devices.
