Description
The Matter-wave Atomic Gradiometer Interferometric Sensor (MAGIS-100), soon to be constructed at Fermilab, uses three coupled light-pulsed atom interferometers across a 100-meter baseline to probe external potentials as low as $10^{-20}$ eV. This sensitivity enables unparalleled reach into unexplored parameter space for ultralight scalar dark matter that couples to electrons or photons with mass above $10^{-15.5}$ eV, providing significant discovery potential. The sensor is also capable of performing searches for new forces, such as a $B-L$ coupled vector boson, when run in a dual-isotope interferometer mode. In addition to these new physics, MAGIS-100 will also be sensitive to gravitational waves in the “mid-band” region of frequency space (0.1 Hz - 10 Hz) between Advanced LIGO and LISA, and can perform precision tests of quantum mechanics at unprecedented length scales. This detector builds on expertise from the 10-meter prototype at Stanford and capitalizes on the latest advancement in atomic clock technology, and will serve as a pathfinder for a future kilometer-scale sensor. In this poster, I summarize the planned scientific program for the experiment and present projected sensitivities for various physics signals.
