The work shows that free-streaming dark radiation isocurvature produces a qualitatively different gravitational wave spectrum than cold dark matter isocurvature and derives constraints on isocurvature power spectra around 10^6 Mpc^{-1} from NANOGrav data.
Collapsing Z_N domain walls trap baryons into dense baryoids, yielding a dark matter-baryon energy density ratio of approximately (N-1):1 after the QCD phase transition.
Collapsing axion-like domain walls generate the baryon asymmetry by acting as an effective chemical potential through coupling to the electroweak topological term, with the asymmetry produced via sphaleron processes.
An ultralight scalar temporarily lowers a dark fermion mass via muon thermal density, opening efficient B meson dark decays for baryon asymmetry generation that later shuts off to match flavor data.
A UV-complete neutron portal model dynamically solves the dark matter-baryon coincidence via a supercooled dark confinement transition that generates GeV-scale asymmetric DM and links to observed gravitational waves.
An axion-like particle's domain wall or shock wave induces an electroweak phase boundary whose motion creates a local B+L chemical potential that biases active sphalerons to generate net baryon asymmetry.
Electroweak-symmetric domain walls produce the observed baryon asymmetry via CP-violating semiclassical forces, transport, sphalerons, and interference between the two wall faces in a singlet-extended Standard Model.
Deuterium-to-hydrogen measurements leave most electroweak baryogenesis parameter space unconstrained while imposing stronger exclusions on alternative baryogenesis models.
