Prof. Ting, a fellow of Americam Physical Society/Condensed Matter Physics, has been actively working on condensed matter theories related to semiconductors, magnetism, superconductivity, and strongly correlated electron systems. He and his group has employed numerous theoretical methods, such as the diagrammatic many body theory, path integral approach, and numerical techniques including Monte-Carlo simulation, exact diagonalization and transfer-matrix method, to investigate various problems in solid state systems. He has more than 300 publications and his recent works are involving a) the study of local physics in cuprate-superconductors (HTS) and Fe based superconductors which directly relates to the STM experiments, b) the interplay between superconductivity and antiferromagnetic order in Fe-pnictide compounds, c) the signatures of the FFLO state in heavy fermion superconductors and in cold atom systems or optical lattices, d) the study of many body effects and transport properties of Dirac fermions in graphene and electrons in bilayer graphene, and e) the physics due to spin-orbit interactions.
