We propose methods to create fractional vortices in the cyclic state of an $F=2$ spinor Bose-Einstein condensate by manipulating its internal spin structure using pulsed microwave and laser fields. The stability of such vortices is studied as a function of the rotation frequency of the confining harmonic trap both in pancake- and cigar-shaped condensates. We find a range of parameters for which the so-called $\frac{1}{3}$ vortex state is energetically favorable. Such fractional vortices could be created in condensates of $^{87}\text{R}\text{b}$ atoms using current experimental techniques facilitating probing of topological defects with non-Abelian statistics.We propose methods to create fractional vortices in the cyclic state of an $F=2$ spinor Bose-Einstein condensate by manipulating its internal spin structure using pulsed microwave and laser fields.

Designing Bose--Einstein Condensate Interferometers

Mark Edwards, Charles W. Clark

Summary form only given. In a recent experiment, performed at the National Institute of Standards and Technology (NIST), a Mach-Zender type matter-wave interferometer was demonstrated using a sequence of laser pulses applied to a gaseous Bose-Einstein condensate. Matter-wave interferometers are essential tools for probing optically manipulated Bose-Einstein condensates (BECs) and the use of a sequence of laser pulses should enable experimenters to implement a variety of interferometer types tailored for particular applications.Summary form only given.

We propose methods to create fractional vortices in the cyclic state of an

F=2

spinor Bose-Einstein condensate by manipulating its internal spin structure using pulsed microwave and laser fields. The stability of such vortices is studied as a function of the rotation frequency of the confining harmonic trap both in pancake- and cigar-shaped condensates. We find a range of parameters for which the so-called

\frac{1}{3}

vortex state is energetically favorable. Such fractional vortices could be created in condensates of
