Time-dependent density of quadratically coupled dark matter around ordinary matter objects
Wavelike dark matter may feature quadratic couplings to ordinary matter. This carries profound consequences for the phenomenologies of such models.

| Riassunto: | Wavelike dark matter may feature quadratic couplings to ordinary matter. This carries profound consequences for the phenomenologies of such models. It changes the dark matter density around dense objects made from ordinary matter such as planets and stars, thereby changing the sensitivity of direct detection experiments on Earth as well as implying forces on other ordinary matter objects in the vicinity. In this paper we study the time dependence of the dark matter field around spherical objects of ordinary matter. This work indicates the timescale on which accelerating objects settle into a stationary state and delineates the applicability of stationary solutions for experimental dark matter tests. We also use this to understand (and effectively eliminate) the infinities in energies, forces, and pressures that appear when naively comparing the total energy around objects with different size but the same total number of ordinary matter particles. |
