We study the s-wave quintet Cooper pairing phase (Spair = 2) in spin-3/2 cold atomic systems and identify various novel features which do not appear in spin-1/2 pairing systems. A single quantum vortex is shown to be energetically less stable than a pair of half-quantum vortices. The half-quantum vortex exhibits the global analogue of the non-Abelian Alice string and SO(4) Cheshire charge in ga...

The role of the (dynamical) dilaton in the vortices associated with the spontaneous breaking of an anomalous U(1) from heterotic string theory is examined. We demonstrate how the anomaly (and the coupling to the dilaton/axion) can appear in the Lagrangian and associated field equations as a controlled perturbation about the standard Nielsen-Olesen equations. In such a picture, the additional fi...

Optical vortices are beams of laser light with screw symmetry in their wavefront. With a corresponding azimuthal dependence optical phase, they convey orbital angular momentum, and methods production applications have become one the most rapidly accelerating areas physics technology. It has been established that quantum nature electromagnetic radiation extends to properties conveyed by each ind...
