The existence of new particles that interact extremely weakly with normal matter is well-motivated, in particular through the observed dark matter of the universe.
We aim to theoretically and experimentally investigate the use of state-of-the-art quantum sensors and ultra-high precision techniques, such as a network of atomic clocks, as probes of such “dark sectors".
Probing dark sectors through a variety of high-precision quantum experiments.
