Researchers from the University of Hong Kong, including Drs. Hongyu Lu, Bin-bin Chen and Prof. Zi Yang Meng, teamed up with Profs. Kai Sun from the University of Michigan and Han-Qing Wu from Sun Yat-sen University, discovered different ways of ordering electrons in 2D quantum materials. In particular, the research team focused on the interplay between smectic order and topological order. The exotic states and thermal phase transitions exhibiting such features are expected to be accessed in future experiments. Continue reading

We are pleased to announce the launch of the official website for the meeting "Fractional Chern Insulators: Theory, Numerics and Experiment."

A recent study, led by Professor Zi Yang MENG and co-authored by his PhD student Menghan SONG of HKU Department of Physics, in collaboration with researchers from the Chinese University of Hong Kong, Yale University, University of California, Santa Barbara, Ruhr-University Bochum and TU Dresden, has unravelled some of the secrets concealed within the deconfined quantum critical points. Their findings, recently published in the prestigious journal Science Advances, push the boundaries of modern physics and offer a fresh perspective on how quantum matter operates at these enigmatic junctures.

 

On April 16, 2025, Mr. Hongyu Lu marked a pivotal achievement by successfully defending his Ph.D. thesis, entitled "Numerical studies of fractional quantum anomalous Hall states: Emergent forms, collective excitations, and phase transitions". His clear and compelling presentation of his research findings from his time at HKU, along with his confident responses to impromptu questions, earned high praise from the Examining Committee, which included Prof. Xi Dai from HKUST, and Profs. Wang Yao and Dong-Keun Ki from HKU. Congratulations to Dr. Hongyu Lu! We wish him continued success and look forward to his contributions as an emerging leader in theoretical condensed matter physics. Continue reading
