new experimental directions
Dark matter particles are constantly streaming through the Earth, though they interact so weakly that we never notice. However, ultrasensitive detectors can be utilized to discover these faint signals. Many experiments are currently probing the parameter space relevant for Weakly Interacting Massive Particles, however new approaches are needed to broaden sensitivity to dark matter of lighter mass. We developed new experimental strategies to search for dark matter down to the keV-MeV range, and collaborated with experimentalists to use co-magnetometers to search for ultralight wave-like dark matter. Additionally, we have studied the unique features of dark matter in such direct detection experiments, including effects such as gravitational focusing and stochasticity.
