A mechanism for formation of Bose-Einstein condensation in cosmology
read the original abstract
We introduce a toy model of scalar particles with a trilinear scalar coupling in cosmology. The trilinear coupling $\phi^2\chi$ causes production of non-relativistic $\phi$ particles through the process $\chi\chi\,\rightarrow\,\phi\phi$ where, initially, only relativistic $\chi$ particles are present. We consider the initial times of $\chi\chi\,\rightarrow\,\phi\phi$ and observe that the curved space effects promote formation of Bose-Einstein condensate of $\phi$ particles.

Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...

Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Vortex reconnections in BEC/superfluid dark-matter cores can transfer at most 0.06–4.5% of the virial energy in 10 Gyr under fiducial assumptions, so they cannot appreciably restructure the core.

Gravitational particle production, the cosmological tensions and fast radio bursts
Gravitational vacuum polarization explains the Hubble tension by increasing direct H0 measurements while leaving indirect ones unaffected, does not impact the sigma8 tension, and predicts FRB measurements match CMB/BA...
