Relaxation times for Bose-Einstein condensation by self-interaction and gravity

  title={Relaxation times for Bose-Einstein condensation by self-interaction and gravity},
  author={Jiajun Chen and Xiaolong Du and Erik W Lentz and David James Edward Marsh},
In this letter, we study the Bose-Einstein condensation of a scalar field with attractive selfinteraction both with and without gravitational interactions. We confirm through full dynamical simulation that the condensation time scale due to self-interaction is inversely proportional to the square of the number density n and the self-coupling constant g (τ ∝ n−2g−2). Our results disprove the recent prediction by Kirkpatrick et al. (2020) [1] that the self-interaction relaxation time is inversely… Expand

Relativistic Axions from Collapsing Bose Stars.
The substructures of light bosonic (axionlike) dark matter may condense into compact Bose stars. We study the collapse of critical-mass stars caused by attractive self-interaction of the axionlikeExpand
Understanding the core-halo relation of quantum wave dark matter from 3D simulations.
From this scaling relation, present dwarf satellite galaxies are predicted to have kiloparsec-sized cores and a minimum mass of ∼10(8)M⊙, capable of solving the small-scale controversies in the cold dark matter model. Expand
On the possibility of Bose-star formation
Abstract The relaxation time of a gravitationally bounded cloud of bosons is estimated for the case of a large phase-space density of particles. The axionic mass and self-coupling relaxation time areExpand
