Atomic Physics

Using lasers and other electromagnetic fields, atomic physicists can exquisitely control the internal and motional states of atoms. We have several experimental groups who apply such control over ions and neutral atoms for studies in quantum information science, many-body physics, and tests of fundamental physical theories.

Associate Professor
Trapped Ion Quantum Computing
We work on experimental implementation of quantum computation and quantum communication using single trapped ions and single photons, and the hybrid atom-photon entangled state. Apart from the quantum information applications, we are also interested in testing the fundamental principles of quantum mechanics. ​

Assistant Professor (joint in EE)
Single-impurity Optoelectronics
​My group focuses on spin-systems in solids for quantum information processing (QIP) and sensing applications. Techniques including pump-probe, optical spin-echo, and high-resolution spectroscopy are used to further understand spin dynamics. Coupled optical-spin systems are integrated into nanophotonic devices to enable optical communications between spins for QIP and to increase magnetic sensitivity in sensing applications. Systems currently studied include semiconductor impurities, semiconductor quantum dots, and color centers in diamond.

Associate Professor
Ultracold atoms
One research theme in our group is the study of interacting quantum mixtures of atoms at 100 nanoKelvins, and preparation and studies of polar diatomic molecules. These systems can precisely explore fundamental few- and many-body physics and are applicable towards quantum simulation and information science. The second is the development of an atom interferometer using Bose-Einstein condensates to measure the fine structure constant and precisely test the theory of quantum electrodynamics.

Tests of parity & time-reversal symmetry
Together with Norval Fortson, I am involved in a precision experiment to determine the electric dipole moment of the mercury atom. This is a sensitive probe for new physics beyond the standard model. I also pursue research in gravitational physics.

Tests of parity & time-reversal symmetry
Experimental searches for an electric dipole moment (EDM) in an elementary particle, atom, or molecule, are ideal probes for new physics beyond the Standard Model, such as supersymmetry. We are performing an experiment which precisely determines the EDM of the mercury atom. Above is an image of part of our mercury EDM experiment. I am also involved with trapped single-ion research.
