Matter influence on large-scale scalar dynamics
Philippe Brax
Local structures in the Universe can influence the dynamics of light scalar fields when coupled to matter. We focus on light test fields evolving in matter modelled as a stochastic…

3D Vortices and rotating solitons in ultralight dark matter
Ph. Brax, P. Valageas
We study the formation and the dynamics of vortex lines in rotating scalar dark matter halos, focusing on models with quartic repulsive self-interactions. In the nonrelativistic re…
