What is Effect of Light-assisted Tunable Interaction on the Position Response Function of Cold Atoms about?

The position response of a particle subjected to a perturbation is of general interest in physics. We study the modification of the position response function of an ensemble of cold atoms in a magneto-optical trap in the presence of tunable light-assisted interactions. We subject the cold atoms to an intense laser light tuned near the photoassociation resonance and observe the position response of the atoms subjected to a sudden displacement. Surprisingly, we observe that the entire cold atomic cloud undergoes collective oscillations. We use a generalised quantum Langevin approach to theoretically analyse the results of the experiments and find good agreement.
