Ping Group’s research focuses on developing theoretical and computational methods such as many-body perturbation theory and first-principles open quantum dynamics based on density-matrix formalism, to understand and predict materials’ properties including optoelectronic, excitonic, and spin dynamics and transport properties at the atomistic levels, for energy conversion, low power electronics, and quantum information applications. Recent research areas have emphasis on the interplay of spin-orbit, light-matter interaction with momentum transfer and optical orientation, symmetry and topology, as well as many-body interactions among electrons and phonons in materials.
