My research group conducts experimental studies on ultracold atomic gases. Ongoing studies aim to gain a deeper understanding of correlated quantum many-body systems, the physics of quantum measurement, the dynamics of isolated quantum systems and novel quantum sensor technologies. Currently, we have three operating laboratories studying the physics of (i) Optical lattice gases, (ii) Spinor quantum fluids and (iii) Hybrid quantum systems.

The first machine is dedicated to the study of optical lattice gases, the interplay between coherent quantum dynamics and measurement, and the use of continuous quantum measurement to coax a quantum system into novel forms of correlated behavior. To perform these studies, we have developed a novel Bose condensate apparatus capable of generating BECs at rapid duty cycles and developed techniques to perform continuous nondestructive measurement of ultracold atoms in optical lattices. Using these techniques, we have recently demonstrated the quantum Zeno effect in an ultracold lattice gas and observed the gradual transition of an ultracold gas from quantum coherent to classical behavior due to the act of measurement. We are currently studying such measurement-induced transitions and methods to create strong quantum correlations through measurements.

The second machine features a BEC-cryostat interface devised to introduce cryogenically cooled devices and materials in close proximity to a Rubidium Bose condensate for applications including micron-scale magnetic sensing and optomechanics. We are currently performing studies of optomechanical systems in a variety of material platforms including silicon nitride membranes, graphene nanoresonators and microtoroidal resonators that are interfaced to ultracold atomic gases. Such hybrid quantum systems are promising platforms for precision measurements, quantum transduction and information processing.

The third machine is dedicated to the study of ultracold spinor gases and fermionic gases of Lithium. We have recently predicted that ultracold spinor gases of Lithium feature strong spin-dependent interactions that lead to qualitatively new forms of bosonic magnetism and interplay between magnetism and superfluidity. We are conducting studies of such spinor gases with the aim of understanding their phase diagram and their out-of-equilibrium behavior. In collaboration with theorists, we have also predicted that spinor gases in Rubidium exhibit robust, ‘prethermalized’ states that persist in nonequilibrium conditions for extremely long durations. Our experiments seek to understand the properties of such 'prethermalized' states and possible universal laws that govern the behavior of such states.
