The authors investigate the formation of Bose-Einstein condensates from axion dark matter, and it is shown that a homogeneous condensate with long range correlations is unstable when $a\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}r\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}c\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}v\phantom{\rule{0}{0ex}}e$ interactions like gravity are taken into account. Instead many Bose-Einstein condensates in form of Bose stars with correlation lengths much below galactic scales are created.

Ultralight scalars as cosmological dark matter (2016, methodology): “The situation is analogous to using the Maxwell equations to describe configurations involving a large number of photons (see [36] for a discussion; see also [37, 38] for the use of the Schrödinger equation in modeling large scale structure).”
Gravitational probes of dark matter physics (2017, background): “The lack of an axion signal would imply that QCD axions are excluded as dark matter unless the vacuum misalignment angle θ 1 or most axions cluster in Bose stars [184].”
