Probing New Physics with Spin-Polarized Systems
点击次数:

Despite its remarkable success, the Standard Model leaves several unresolved questions, such as the strong CP problem and the nature of dark matter. Dark matter research represents one of the most important frontiers in fundamental physics, with axions being a leading candidate. Axions not only potentially explain dark matter but may also resolve the strong CP problem. They are also predicted to mediate new interactions beyond the four fundamental forces (a "fifth force").

Our research group specializes in using spin-based systems to detect dark matter candidates such as axions and dark photons. We have developed a suite of precision spin-based magnetometers, including atomic magnetometers and novel levitated ferromagnetic resonator sensors. The fermion spins (e.g., neutrons, protons, electrons) in these sensors can couple with dark matter particles or detect weak magnetic fields induced by dark matter, enabling both direct and indirect detection (via fifth-force interactions).

Additionally, these advanced sensors are capable of detecting other fundamental signals, such as gravitational waves and neutrinos. Through high-sensitivity measurement techniques, we aim to push the boundaries of fundamental physics, providing new experimental tools and methods to unravel the mysteries of the universe.
