Professor Go Yusa, Assistant Professor Masahiro Hotta, visiting student Quentin France (graduate student at Sorbonne University, France), graduate student Yunhyon Jeong, and Dr. Akinori Kamiyama, in collaboration with Nippon Telegraph and Telephone Corporation (NTT) and the National Institute for Materials Science (NIMS), have successfully captured video footage of electron waves propagating along the edge and through the bulk of a special electronic state known as a fractional quantum Hall liquid.
The achievement was made possible using a scanning, polarization-selective photoluminescence microscopy system capable of operating under extreme conditions of ultra-low temperature and high magnetic field. This breakthrough paves the way for experimental simulations that could test bold concepts in extreme-universe physics, such as the brane-world hypothesis and the holographic principle.
The results of this research were published online in the physics journal Physical Review Letters on August 5, 2025 (U.S. Eastern Time).
