HKIQST Co-Hosts the APS Global Physics Summit 2026 in Hong Kong| Monday, 23-27 March 2026 | HKPC Building, HK

HKIQST is proud to co-host the APS Global Physics Summit 2026 Hong Kong Meeting, offering researchers across the Asia-Pacific region the most accessible pathway to participate in this premier international physics gathering. Dual Access: Registration for the Hong Kong meeting includes full online access to the APS Global Physics Summit (15–20 March 2026), at a significantly reduced cost compared to direct APS registration. Participants can attend live-streamed talks, revisit recordings for 90 days, and explore e-posters without additional fees. Abstract Submission: Oral abstracts submitted by 5 January 2026 may be selected for inclusion in the official APS Virtual Session. On-Site Programme: The Hong Kong meeting (23–27 March 2026) will feature a dynamic in-person academic environment, with oral and poster presentations, networking opportunities, and engagement with a diverse community of physicists from across the region. 📍 Venue: Hong Kong Productivity Council, Kowloon Tong 🤝 Organised jointly with PSHK, and supported by APS, HKIQST, and Qebula Mind Ltd.

“Towards Semiconductor Topological Photonics” by Prof. Xiao HU on Monday, January 12, 2026, 2:00pm CYM522, HKU

Transforming the concept of band topology fostered in electron systems to electromagnetic waves opens a completely new direction for harnessing propagation of light. It is observed that electromagnetic modes in honeycomb photonic crystals exhibit Dirac-type frequency dispersions, which are accompanied by emergent spin degree of freedom, and that deforming the honeycomb structure in a designed way gives birth to a photonic analogue of quantum spin Hall effect. In this talk I will first show that the main physics can be captured phenomenologically by the k∙p theory, and discuss that the photonic topology can be characterized in terms of the Wilson loops based on the C_2 T symmetry. Then I will introduce examples to demonstrate how the recipe can be exploited for harnessing light and deriving advanced optic properties.
