UBC Prof. Takamasa Momose garners place in Physics World Top 10 Greatest Achievements
The Department of Physics & Astronomy warmly congratulates Dr. Takamasa Momose on being recognized by Physics World for contributing to one of the Top 10 Breakthroughs of the Year for 2025.
Professor Momose, together with Susumu Kuma of the RIKEN Atomic, Molecular and Optical Physics Laboratory and their collaborators, successfully observed superfluidity in liquid hydrogen clusters. Using methane as a probe, the team was able to observe the rotational behaviour of hydrogen molecules. This phase of molecular hydrogen, first theorized in 1972, had never before been directly observed at the molecular level.
This achievement—representing the culmination of more than 20 years of research—advances understanding of quantum phase transitions. As Professor Momose explains, “This discovery deepens our understanding of quantum fluids and could inspire more efficient hydrogen storage and transport for clean energy.”
Professor Momose is an expert in cold molecules at UBC and the senior author of the study. He holds a joint appointment with the UBC Department of Chemistry and the Department of Physics & Astronomy, working with colleagues Valery Milner and Kirk Madison in the field of Atomic, Molecular and Optical Physics.
Physics World’s Top 10 Breakthroughs of the Year for 2025 highlights exceptional research from across physics, including advances in astronomy, antimatter, and atomic and molecular physics. Selected breakthroughs represent significant advances in understanding, have a clear impact on scientific progress, and are of broad interest to Physics World readers.
