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…
Self-Interaction Controls Vortex Scale in Soliton Mergers
Yuanyuan Zeng, Bokai Zhang, Jiajun Chen
This study investigates the impact of self-interaction strength on the formation and scale of turbulent vortex structures during the merger of Bose stars, using numerical simulatio…
Novel structures and collapse of solitons in nonminimally gravitating dark matter halos
Jiajun Chen, Hong-Yi Zhang
Ultralight dark matter simulations predict condensates with short-range correlation, known as solitons or boson stars, at the centers of dark matter halos. This paper investigates…
