Universal gravitational waves from interacting and clustered solitons

Universal gravitational waves from interacting and clustered solitons

Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller than scales of nonlinearity. We show that modifications of the soliton density field, driven by soliton interactions or ini...
