Randomness and Warmth (and spin) in Wave Dark Matter: [APEC]

Description
If wave dark matter density is dominated by subhorizon field modes in the early universe, then the field exhibits Poisson fluctuation related enhancement on small scales, as well as warmth. These lead to scale dependent growth of structure, which leaves free-streaming, Jeans and shot-noise related features in the linear matter power spectrum as well as halo mass function. They also lead to significant soliton formation after matter radiation equality. I will discuss a general analytical framework as well as numerical results for the growth of structure in such systems, including cases with different species having different amounts of warmth and Poisson fluctuations, as well as species with different spin.
