Description
Axions (and axion-like particles) produced by the vacuum realignment
mechanism in the early universe form a highly degenerate Bose gas
and are a cold dark matter candidate. Dark matter axions thermalize as a result of their gravitational self-interactions when the photon temperature reaches approximately 500 eV. When thermalizing, the axion fluid undergoes Bose-Einstein condensation, a quantum process.
A formalism is introduced to help calculate the outcome of this
process.
