Two distinguished scholars at The Hong Kong University of Science and Technology (HKUST) – Professor Jensen Li Tsan-hang and Assistant Professor Dr. Berthold Jäck, both from the Department of Physics, were recently awarded the prestigious 2022 Croucher Senior Research Fellowships, and the Croucher Tak Wah Mak Innovation Awards 2022 by The Croucher Foundation.
Prof Li’s research revolves around various extraordinary optical phenomena given by metamaterials, with prominent examples such as invisibility cloaking and super-resolution imaging. His current interests are in transformation optics, metasurfaces, non-Hermitian optics and complex media. Metamaterials promise to provide exotic material properties based on tailor-made resonating micro-structures to provide material parameters that do not exist in conventional approaches. With the Croucher Senior Research Fellowship, he will explore new dimensions in constructing and applying metamaterials using non-Hermiticity from material gain and loss, time-varying capability of material parameters, currently known as time-varying metamaterials and applications of metamaterials in the quantum optical regime. These metamaterials can be applied to create very sensitive sensors, to achieve non-reciprocal signal communications and to develop new techniques in quantum imaging.

Dr Jäck’s research focuses on the fabrication and characterization of novel quantum materials that could facilitate energy-efficient electronic devices and new types of quantum computers. Placed at the interface of condensed matter physics and material science, his research aims to augment the microscopic interactions between charge carriers and magnetic moments through judicious materials design resulting in novel quantum phenomena. To this end, Dr Jäck combines thin film material growth using molecular beam epitaxy with the microscopic and macroscopic material characterization using scanning tunnelling microscopy and electrical transport measurements, respectively. Developing novel microscopy methods to study charge carrier dynamics with high spatial and temporal resolution, Dr Jäck’s ultimate research goal is exploring new frontiers in quantum materials research.
