Title: Quantum ferrofluid turbulence,
Abstract: We study the elementary characteristics of turbulence in a quantum ferrofluid
through the context of a dipolar Bose gas condensing from a highly
non-equilibrium thermal state. Our simulations reveal that the dipolar
interactions drive the emergence of polarized turbulence and density
corrugations. The superfluid vortex lines and density fluctuations adopt a
columnar or stratified configuration, depending on the sign of the dipolar
interactions, with the vortices tending to form in the low density regions to
minimize kinetic energy. When the interactions are dominantly dipolar, the
decay of vortex line length is enhanced, closely following a $t^{-3/2}$
behaviour. This system poses exciting prospects for realizing stratified
quantum turbulence and new levels of generating and controlling turbulence
using magnetic fields.
