Welcome to Prof. Di Xiao's research group in the Physics Department at Carnegie Mellon University.
We study a variety of problems in theoretical condensed matter physics. Currently, our research efforts are directed towards understanding and predicting material properties (transport, magnetic, and optical) from the viewpoint of Berry phase and topology. In particular, we are interested in topological phenomena arising from spin-orbit coupling and many-body interactions. These phenomena are often characterized by novel electromagnetic responses, which may be useful for applications in quantum electronics and quantum computing.
Recent topics of interest in the group are
- Valley electronics in 2D crystals, e.g., graphene and MoS2;
- Topological states in transition metal oxides;
- Charge and spin transport in spin-orbit coupled materials.
