In superfluid dark matter (SFDM), the phonon field plays a double role: It carries the superfluid's energy density and it mediates the MOND-like phonon force. We show that these two roles are in tension with each other on galactic scales: A MOND-like phonon force is in tension with a superfluid in equilibrium and with a significant superfluid energy density. To avoid these tensions, we propose a model where the two roles are split between two different fields. This also allows us to solve a stability problem in a more elegant way than standard SFDM. We argue that the standard estimates for the size of a galaxy's superfluid core need to be revisited.

Bridging Superfluid and Nonminimally Coupled BEC Dark Matter through RAQUAL
SFDM's phonon–baryon force maps onto BECDM's non-minimal Einstein-tensor coupling plus a small Ricci coupling, but the non-analytic kinetic term prevents full dynamical equivalence.

Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...
