Showing papers by "Alan H. Guth published in 2015"
TL;DR: 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 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.
