Atomic physics techniques used in timekeeping, precision spectroscopy, and atom interferometry are poised to become powerful tools for discovery. Future experiments can set new limits on the equivalence principle, test quantum mechanics, and directly probe general relativistic effects in a laboratory environment. Atomic physics also offers compelling strategies for detecting gravitational waves. Gravitational waves antennas will provide a new window into the universe, collecting information about astrophysical systems that are difficult or impossible to observe optically, and teaching us about cosmology by seeing where other telescopes cannot, even to the earliest times in the universe.
Professor Hogan's research is focused on increasing the sensitivity and accuracy of atomic sensors to pursue these science goals. To this end, the group develops novel methods to generate quantum superposition states of atoms that are simultaneously localized in two macroscopically separated positions at once, and that maintain coherence for many seconds. These extreme atom wavepacket separations push the limits of what can be done with quantum objects, testing our understanding of quantum mechanics. To build a gravitational wave detector prototype, the group is studying atom interferometry using optical clock atoms in order to take advantage of the increased noise immunity that is predicted for these systems.
