Bose-Einstein condensates of 100,000 ⁸⁷Rb atoms following a Ramsey interference experiment. Each image corresponds to a different evolution time of the condensate (inset in milliseconds), during which its phase develops spatial inhomogeneity. (Top) Experimental absorption images, (Bottom) Theoretical simulations of the Gross-Pitaevskii equation.

Spinor Bose-Einstein condensate of of ⁸⁷Rb undergoing Rabi oscillations. A radiofrequency pulse of variable duration is applied, driving transitions between the Zeeman states of the F = 2 ground level. The reuslting superposition is imaged using the Stern-Gerlach technique: the components of the condensate with distinct quantised spin projection are resolved by applying a subsequent magnetic field gradient.

RESEARCH INTERESTS

I am an experimental atomic physicist exploring ultracold quantum gases. My research focus is Bose-Einstein condensates with a spin degree of freedom: spinor and pseudospior BECs. In addition to the myriad topological phenomena they exhibit, these exotic superfluids are promising candidates for trapped atom interferometry and high resolution magnetometry.

Specific research interests include

• spinor condensate dynamics,
• multi-component superfluidity,
• trapped atom interferometry,
• spin squeezing,
• wavefunction engineering,
• matter-wave phase retrieval, and
• coherent control of ultracold collisions.

Marrying experiments in all of the above with the techniques of magnetic resonance is an ongoing theme of my research.
