Research Overview

Dr. Hsiang-Hua Jen's research expertise lies in theoretical quantum optics and ultracold atoms, with a primary focus on atom–nanophotonic waveguide interfaces, non-Hermitian physics, and quantum correlations in dense atomic ensembles. These theoretical investigations aim to uncover the essential principles of quantum engineering through collective interactions between neutral atoms and light, with potential applications in quantum science and quantum technologies.
