Research Interests

Ordinary matter like atoms and stars accounts for less than 5% of the contents of the Universe. The existence of the so-called “dark energy” and “dark matter” that dominate the Universe is still beyond our understanding. Even the ordinary part of the Universe is full of big unanswered questions. For example, mysterious imbalance between matter and antimatter, impenetrable synthesis of heavy elements and evolution of stars, enigmatic ultra-high energy cosmic rays, and the puzzling neutron lifetime anomaly have been long-standing problems in fundamental physics. By introducing a new particle-oscillation mechanism, I have recently developed a new mirror-matter model and its underlying theory for extending standard model with mirror matter that can, if experimentally verified, solve all the above puzzles.

My research interests lie in further theoretical development of the mirror-matter theory and various novel experimental tests on the new theory. Such laboratory experiments include neutron decay measurements using magnetic traps with different shapes, resonant neutron oscillation search under super-strong magnetic fields, neutral kaon invisible decays, 11Be invisible decays, etc. This new research direction will help us discover new physics and better understanding the mirror sector of the Universe.

My other interests include nuclear astrophysics, i.e., various nuclear processes in stars, in particular, phenomena related to the above-mentioned mirror matter theory.
