Radio frequency Ramsey interferometry with an F=1 spinor Bose-Einstein condensate
ORAL
Abstract
We report on a RF Ramsey interferometric measurement on the F = 1 ground state of our sodium Bose-Einstein condensate (BEC). Due to the spin-1 ground state level structure, the fringe pattern exhibits a more complicated beat-like structure, compared to the typical spin-½ case. We explore the theoretical origins and behavior of this more complicated spin-1 Ramsey signal, and demonstrate a measurement of our RF detuning to a precision of the order of 100 Hz or better. We further discuss its usefulness for the calibration of spin-1 BEC experiments.
