The 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 emphasized 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.
