  What our universe could be if it has higher spatial dimensions beyond three dimensions (3D)? To answer this question satisfactorily is really hard and challenging, though it is quite intriguing and fundamental in physics. Fortunately and interestingly, topological insulators are ideal physical systems to display novel phenomena in higher dimensions simply because topological features are critically sensitive to spatial dimensions. Based on some experimental advances of higher-dimensional physics in synthetic matter, in this talk, I will present two of our recent work about novel topological phases in 4D. In particular, various topological quantum-responses, including electromagnetic ones, from the four-dimension bulk-system to its 3D boundary have been predicted, and meanwhile a host of exotic topological phase transitions have been revealed, with very rich phase diagrams being discovered. It is believed that these work will be of great interest to the wide physics communities, which can further open new directions for exploring topological world in higher dimensions in terms of the innovative approach developed here.
