Image of the Week: An embedded Rydberg aggregate

In their recent paper Exciton induced directed motion of unconstrained atoms in an ultracold gas K Leonhardt et al show that it is possible to use localised Rydberg excitation in a cloud of cold atoms to direct atomic motion and to confine it to a plane.  This occurs with no need to spatially constrain the motion of the atoms.  Published as part of the JPhysB Special Issue on Rydberg Atomic Physics, their results suggest that Rydberg aggregates can be used to examine quantum chemical effects in experiments across large distance scales.

Embedded Rydberg aggregate. Four excitation beams (red shades) define focus volumes in which exactly one atom is excited to a Rydberg state (blue balls, 1–4), within a cold gas (green balls).
