Planetary Defense and Space Quantum Technologies for Fundamental Physics: Dark Matter, Gravity, Fifth Forces, and Cosmic Neutrinos

Event Details

In this talk, I will talk about using planetary/asteroidal data and space quantum technologies to study fundamental physics. We first show a proposal using space quantum clocks to study solar-halo ultralight dark matter, motivated by the NASA deep space atomic clock (DSAC) and Parker Solar Probe (PSP). We then discuss new constraints on fifth forces using asteroidal data. We will show preliminary results of the robust constraints by using the NASA JPL program and asteroid tracking data that are used for planetary defense purposes. We then discuss model-independent constraints on any dark matter models through pure gravity.
The talk is largely based on and, but will also contain completely new results and realistic analysis conducted in collaboration with NASA planetary defense experts.
