Core-Halo Mass Relation in Cosmological Vector Dark Matter
Jiajun Chen, Yonghao Yao, David J. E. Marsh
We study the cosmological core-halo relation in vector dark matter using three-component Schrödinger-Poisson simulations. Starting from cosmological vector-field initial conditions…

Spin Polarization of Proca Stars Formed by Gravitational Bose--Einstein Condensation
Jiajun Chen
We study the internal spin polarization of Proca stars formed by gravitational Bose--Einstein condensation of a three-component nonrelativistic vector field. In idealized periodic-…

Yukawa-Screened Bose-Star Condensation
Jiajun Chen
We study Bose-star formation in a Yukawa-Schrödinger-Poisson (YSP) system. A finite interaction range suppresses the infrared kinetic relaxation responsible for Bose-star condensat…
