Abstract: Traditional Ginzburg-Landau paradigm successfully describes a large set of phenomena in solids. In this framework, phases of matter are ultimately characterized by emergent classical order parameters, even if the microscopic degrees freedom are quantum mechanical. However, recent experimental progresses in quantum solids force us to look into new patterns of emergence, or new types of orders, that are intrinsically quantum mechanical. I will first review the different types of topological phases in solids, including topological insulators, quantum spin liquids and fractional Chern insulators. Then I will talk about their possible realizations in certain transition metal oxide heterostructures. Finally, I will present our recent attempt to systematically describe these new types of orders in a unified theoretical framework. |
