Toward Cracking the Neutrino Quantum Problem Behind Nature’s Most Explosive Events
Achieving a full understanding of the most catastrophic cosmic events—like supernovae and neutron star mergers—has long been hindered by the mysterious quantum behavior of neutrinos, tiny particles whose collective quantum oscillations play a crucial role. Physicists from IoP (Dr. Meng-Ru Wu and Dr. Manu George) and collaborators (Dr. Zewei Xiong at GSI, Germany and Dr. Chun-Yu Lin at NCHC, Taiwan) have recently made significant progress in cracking this problem. Through advanced quantum kinetic transport simulations, they discovered that the most relevant quantum oscillations on microscopic scales average out over larger scales, enabling this effect to be accurately modeled using a simple effective classical transport framework. This innovative approach significantly reduces computational challenges, paving the way for astrophysicists to conduct detailed simulations that could revolutionize our understanding of these explosive phenomena. The research has been published on February 7, 2025 in Physical Review Letters.
