274 citations recorded by the source corpus.

We review recent developments in axion cosmology. Topics include axion cold dark matter, axions from topological defects, axion isocurvature perturbation and its non-Gaussianity, and axino/saxion cosmology in a supersymmetric axion model.

• Do dark matter axions form a condensate with long-range correlation? (2014, background): “Since the axion is primarily governed by attractive interactions—gravitation and scalar-scalar contact interactions—we conclude that while a Bose-Einstein condensate is formed, the claim of long-range correlation is unjustified.”
