# Raman fingerprints on the Bloch sphere of a spinor Bose–Einstein condensate

@article{Schultz2016RamanFO, title={Raman fingerprints on the Bloch sphere of a spinor Bose–Einstein condensate}, author={Justin Tyler Schultz and A. Hansen and Joseph D. Murphree and Maitreyi Jayaseelan and N. P. Bigelow}, journal={Journal of Modern Optics}, year={2016}, volume={63}, pages={1759 - 1767} }

We explore the geometric interpretation of a diabatic, two-photon Raman process as a rotation on the Bloch sphere for a pseudo-spin- system. The spin state of a spin- quantum system can be described by a point on the surface of the Bloch sphere, and its evolution during a Raman pulse is a trajectory on the sphere determined by properties of the optical beams: the pulse area, the relative intensities and phases and the relative frequencies. We experimentally demonstrate key features of this…
