Nonrelativistic superfluids in cosmology from a relativistic approach: Revisiting two formulations of superfluidity
Aline Favero, Heliudson Bernardo
Two formulations of superfluidity are reviewed: Landau's phenomenological two-fluid model and a relativistic effective field theory description. We demonstrate how the two-fluid fo…
Superfluid dark matter flow around cosmic strings
Heliudson Bernardo, Robert Brandenberger, Aline Favero
We consider a cosmic string moving through a gas of superfluid dark matter (SFDM) particles and analyze how it affects the dark matter distribution. We look at two different cases:…
Addressing the Hubble and Tensions with a Kinetically Mixed Dark Sector
Stephon Alexander, Heliudson Bernardo, Michael W. Toomey
We present a kinetically mixed dark sector (KMIX) model to address the Hubble and tensions. Inspired from string theory, our model includes two fields: an axion, which plays…
