Cooperative Effects

We investigate the cooperative effects on optical forces in a system of N two level atoms confined to a volume of dimension less than λ3, where λ is radiation wavelength and driven by a coherent radiation field with a spatial profile like Laguerre–Gaussian or ideal Bessel beam. We show a dramatic enhancement on optical forces as well as on the angular momentum imparted to the atom by a factor of N2.
