Web22 Dec 2016 · We study cosmological structure formation with ultralight axion dark matter, or ``fuzzy dark matter'' (FDM), using a particle-mesh scheme to account for the quantum pressure arising in the Madelung formulation of the Schr\"odinger-Poisson equations. Subpercent-level energy conservation and correct linear behavior are demonstrated. … WebUltralight axion DM can be tested by a future nuclear clock experiment , torsion balances , and atom interferometers such as AION and AEDGE through axion DM's CP-violating couplings. These experiments will probe axion DM–induced oscillations of fundamental constants like electron mass, nucleon mass, and the fine structure constant via the CP …
