NTNU Physicists Achieve Multilevel Photomemory via Vortex Light

A research group led by Professors Yen-Wen Lan and Ting-Hua Lu of the Department of Physics, in collaboration with PhD student Yeh-Ru Chen, master’s student Po-Wen Wang, and postdoctoral researcher Wen-Hao Chang, has published new findings in the October 2025 issue of Science Advances. The article, titled “Orbital angular momentum–driven multistate photomemory,” presents a method for achieving multilevel photomemory utilizing the orbital angular momentum (OAM) of light. This work marks a departure from the binary constraints of conventional optical memory and establishes the angular momentum of light as a viable and independent parameter for information storage and control.

Resonance Across Borders: Teaching Exchange Between NTNU and the University of Texas at Austin and the “A Thousand Miles, A True Talent” Concert

A faculty delegation from the Butler School of Music at the University of Texas at Austin visited National Taiwan Normal University (NTNU) on October 30 and 31. As part of the visit, the professors conducted teaching demonstrations, delivered lectures, and gave a faculty concert in NTNU’s Historic Auditorium. The two universities have maintained a longstanding partnership, with regular academic and artistic exchanges, particularly in music and the performing arts.

NTNU is Working with Caltech to Advance Quantum Memory Tech

A recent collaboration between the Department of Physics at National Taiwan Normal University and the California Institute of Technology (Caltech) has successfully overcome a key bottleneck in quantum memory technology. The study demonstrates that at extremely low temperatures, a magnetic field induces polarity ordering in monolayer molybdenum disulfide (MoS₂) transistors. This breakthrough is poised to bring revolutionary changes to the development of two-dimensional materials and electronic technologies.

NTNU Leads New Thinking in Asia-Pacific Teacher Education: Teacher Preparation Becomes a Global Focus in the AI Era

The 2025 Annual Conference of the Asia-Pacific Association for Teacher Education (APATE) was successfully held at National Taiwan Normal University (NTNU) from October 17 to 18. Under the theme “Teacher Education in the Age of AI: Making a Difference in the Asia-Pacific Region,” the event brought together educational leaders and scholars from more than ten countries across Asia, the Americas, and Europe to explore new directions in teacher development and educational innovation amid the rise of artificial intelligence.

Deep Aseismic Slip Identified as a Key Precursor to the 2024 Hualien Earthquake

A research team led by Professor Hui-Hsuan Chen of the Department of Earth Sciences at National Taiwan Normal University (NTNU) has found evidence that accelerated aseismic slip on a deep fault began as early as three years before the magnitude-7.3 Hualien earthquake on April 3, 2024. This behavior suggests features of a potential earthquake precursor. The team’s findings, published in Nature Communications, offer important insight into how major earthquakes may develop over long timescales and highlight the role of slow slip along the Central Range Fault in eastern Taiwan.
