Unified Superfluid Dark Sector

10% today, for the parameters chosen for the model, which is a difference that can
be probed by future experiments.
Vortices Quantum vortices are a prediction of superfluids rotating faster than the
critical angular velocity and its measurements would be a smoking gun for the
superfluid model. To calculate the abundance and properties of those vortices, it
is necessary to have a full microscopic description of the superfluid. This topic is
worth further investigation since the detection of such effect would be an important
evidence for the presence of superfluids in galaxies.
For a review of other effects of the DM superfluid in galaxies and clusters, one
can see [8, 9, 14]
Acknowledgments I would like to thank Justin Khoury, Robert Brandenberger, and Guilherme
Franzmann for the most enjoyable and exciting collaboration. I would also like to warmly thank the
organizer of the QTS-XI for the stimulating conference and the invitation to speak in the cosmology
session.
