The duality of matter and anti-matter: from gravitation to neutron star

Abstract

Rare in our universe, antimatter may provide tremendous energy supply through matter-antimatter annihilation. Although continuous efforts have been made on the search of new antiparticles, the mechanism on the generation and transformation of anti-matter remains fully understood yet. Here we propose a dual matter-antimatter model based on quantum coherence of the two states interchanged under mass conjugation, which allows a consistent transition between matter/antimatter and massless radiation in a general nonadiabatic framework. The model not only offers a new perspective for the symmetric universe picture, but also suggests a mechanism of neutron star evolution regarding to the balance between gravitational energy and mass energy. The mechanism predicts a phase transition from the neutron/antineutron mixture to the zero-mass neutral pair, i.e. graviton, which may elucidate the power source of relativistic jet ejection or massive explosion related to unusual astronomical objects such as supernovae, quasar, and active galactic nuclei. The duality of matter and antimatter therefore may provide new physical insights into the understandings of our universe.
