Turbulence and large-scale structures in self-gravitating superfluids
Year: 2025
Type: article
Abstract: A system of self-gravitating bosons can form massive condensates, such as dark matter halos around galaxies. Studying such systems can help constrain the nature of dark matter. Yet, the role of turbulence and vortex dynamics within these structures remains elusive. Using direct numerical simulations of the Gross-Pitaevskii--Poisson equation, we show that halos like structures form through a sequential collapse --- from sheets to cylinders to spheres. The resulting tangled vortical state alters energy transfer across scales, revealing a pathway for the emergence of large-scale cosmic structures.
