Superheavy Dark Matter Production from Symmetry Restoration First-Order Phase Transition During Inflation
Haipeng An, Xi Tong, Siyi Zhou
We propose a scenario where superheavy dark matter (DM) can be produced via symmetry restoration first-order phase transition during inflation triggered by the evolution of the inf…
Perturbative unitarity and NEC violation in genesis cosmology
Yong Cai, Ji Xu, Shuai Zhao +1
Explorations of the violation of null energy condition (NEC) in cosmology could enrich our understanding of the very early universe and the related gravity theories. Although a ful…
Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics
Robert Caldwell, Yanou Cui, Huai-Ke Guo +34
Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture…
Gravitational Waves from an Inflation Triggered First-Order Phase Transition
Haipeng An, Kun-Feng Lyu, Lian-Tao Wang +1
Large excursion of the inflaton field can trigger interesting dynamics. One important example is a first-order phase transition in a spectator sector which couples to the inflaton.…
