Symmetry and topology are fundamental notions existing in all kinds of natural systems, from spiral galaxies and hurricanes to amino acids in molecules and non-trivial topologically protected electronic states in condensed matter. Most notably, the intrinsic capability of photonics of superposing non-Hermitian eigenstates through optical gain and loss provides a powerful toolbox for exploring the symmetry paradigms that were deemed challenging in condensed matter systems. The overarching objective of our research is to explore different quantum symmetry and topological paradigms in a synergistic way for the design of complex optical response and the execution of unique light-matter interactions. This objective will both deepen our understanding of fundamental quantum physics and facilitate technological breakthroughs for photonic applications.
Current research projects in our group span Structured Light with Orbital Angular Momentum (OAM), Non-Hermitian and Topological Photonics, Supersymmetric (SUSY) Optics, and state-of-art Photonic Quantum Technology.
