Ziyun Li is a PhD student in Physics at the Hong Kong University of Science and Technology (HKUST), having commenced her studies in Autumn 2024. Her research centres on quantum phenomena in transition metal dichalcogenide (TMD) moiré superlattices, investigating twisted homo-bilayers and heterostructures engineered through precise twist-angle control. These moiré potentials give rise to a range of exotic electronic phases, including fractional Chern insulators, superconductivity, correlated insulating states, and topological phases. Li employs low-temperature photoluminescence (PL) spectroscopy—often under external magnetic fields—to probe excitonic signatures that sensitively reveal emergent quantum states and underlying material properties. Through this work, she aims to uncover novel quantum matter in highly tunable platforms and contribute to the foundational design principles guiding future topological quantum devices and neuromorphic optoelectronic technologies.
