Quantum magnetism with alkaline-earth atoms

In this research area, we take advantage of the unique internal structure of ultracold alkaline-earth atoms (atoms in the second column of the periodic table) for quantum computing and clock applications, as well as for studying exotic many-body physics. Our work on many-body interactions in an optical lattice clock was published in Science and featured by the New Scientist, ElectronicsWeekly.com, Science World Report, and other news media.
