Description
We investigate the strength and linewidth of a transition between two RF-Dressed ground
states for Rubidium-87 in a non-uniform magnetic field. The linewidth of the selected transition
is broadened due to a mismatch of trapping potentials. This arises from a difference in Land´e
g-factor magnitude between the two hyperfine ground states. A scheme is presented wherein the
magnetic field dependence of the transition frequency between two RF-dressed Rubidium-87
states is reduced by the introduction of a microwave dressing field, increasing coherence times
and reducing transition linewidth [1]. Preliminary measurements are presented with the outlook
of incorporating this method into the operation of a chip-based atom interferometer [2].
