Solitosynthesis and Gravitational Waves

Understand

We study the gravitational wave phenomenology in models of solitosynthesis.

• In such models, a first order phase transition is precipitated by a period in which non-topological solitons with a conserved global charge (Q-balls) accumulate charge.
• As such, the nucleation rate of critical bubbles differs significantly from thermal phase transitions.
• In general we find that the peak amplitude of the gravitational wave spectrum resulting from solitosynthesis is stronger than that of a thermal phase transition and the timescale of the onset of nonlinear plasma dynamics is comparable to Hubble.
