Freeze-in gravitational waves and dark matter in warm inflation
Quan Chen, Siyu Jiang, Dayun Qiu +2
Recent study [1] has suggested that warm inflation may be realized with a minimal extension of the Standard Model by a single scalar inflaton field with an axion-like coupling to g…
A New Source of Phase Transition Gravitational Waves: Heavy Particle Braking Across Bubble Walls
Dayun Qiu, Siyu Jiang, Fa Peng Huang
Motivated by the new heavy dark matter production mechanism from cosmic phase transition, we propose a novel mechanism for the generation of microscopic gravitational waves (GWs) d…
Macroscopic Dark Matter under siege: from White Dwarf Data to Gravitational Wave Detection
Siyu Jiang, Aidi Yang, Fa Peng Huang
The nature of dark matter (DM) remains a profound mystery. Macroscopic candidates, such as Fermi-balls, offer a distinct alternative to conventional particle DM, yet their low numb…
Pseudo-Goldstone Dark Matter from Primordial Black Holes: Gravitational Wave Signatures and Implications for KM3-230213A Event at KM3NeT
Siyu Jiang, Fa Peng Huang
In many well-motivated new physics models, the pseudo-Nambu-Goldstone boson (pNGB) from U(1) symmetry breaking emerges as a promising dark matter candidate. Its coupling, suppresse…
