Research Activities/SpecialtiesMy current research interests aim at understanding theoretical aspects of condensed matter systems, and their possible connections to experiments.
Two recent research focuses are:
1. Topological phases of matter, including symmetry protected topological order, intrinsic topological order, topological spin liquid, and fractionalization of quantum numbers in quantum many-body systems. This part of research mainly relies on the tool of quantum field theory and conformal field theory (such as the use of functional integral, mean-field approximation, Abelian and non-Abelian bosonization, renormalization group, group theory and topology, duality and solvable models).
2. Frustrated magnetism and exotic quantum phenomena, such as layered triangular Ising-spin system, layered quantum Heisenberg-spin system, spin liquid and spin ice material, and unconventional superconductivity. For this part of the research, besides performing analytical analysis and numerical simulations, collaborating with condensed matter experimentalists are also encouraged.
Outside of condensed matter physics, I also have long-standing interests in fundamental aspects of quantum field theory and their application to statistical mechanics and quantum information science.
