|Title:||Ultralight Axion Dark Matter: Detectability, Constraints, and Model Building|
|Date (JST):||Tue, Oct 06, 2020, 13:15 - 14:30|
A number of proposed and ongoing experiments search for axion dark matter with a mass nearing the limit set by small scale structure . However, such models are constrained by the requirement that they yield a matter-power spectrum that matches that of cold dark matter.
I will review current and future experimental efforts to detect ultralight axion dark matter and discuss the implications of the matter-power spectrum bound on these experiments. I will also discuss model building techniques to alleviate the bound and their viability to produce detectable ultralight axion dark matter.
