Simulating Dark Matter Detection Through Nuclear Magnetic Resonance (NMR)

While dark matter remains elusive, a successful detection seems to require unconventional approaches with high sensitivity for small signals. One of the proposed methods to directly probe dark matter is the utilization of pulsed nuclear magnetic resonance (NMR) to measure an oscillating torque on nuclear spins exerted by the axion-like dark matter's oscillating magnetic field. For this project, we use the software our lab has developed, PULSEE (Program for the Simulation of Nuclear Spin Ensemble Evolution), to simulate NMR experiments to observe effects from dark matter particles. Our simulation shows distinct observables which can be identified as signal from dark matter in the case that axion-like dark matter interacts with our system. With these results, we propose that an NMR experiment on low-temperature superfluids with very high gyromagnetic ratio values will be extremely sensitive to external signals such axion particles, allowing us to distinguish signals from dark matter.
