Query: Tailored long range forces on polarizable particles by collective
  scattering of broadband radiation   Collective coherent light scattering by polarizable particles creates
surprisingly strong, long range inter-particle forces originating from
interference of the light scattered by different particles. While for
monochromatic laser beams this interaction decays with the inverse distance, we
show here that in general the effective interaction range and geometry can be
controlled by the illumination bandwidth and geometry. As generic example we
study the modifications inter-particle forces within a 1D chain of atoms
trapped in the field of a confined optical nanofiber mode. For two particles we
find short range attraction as well as optical binding at multiple distances.
The range of stable distances shrinks with increasing light bandwidth and for a
very large bandwidth field as e.g. blackbody radiation we find a strongly
attractive potential up to a critical distance beyond which the force gets
repulsive. Including multiple scattering can even lead to the appearance of a
stable configuration at a large distance. Such broadband scattering forces
should be observable contributions in ultra-cold atom interferometers or atomic
clocks setups. They could be studied in detail in 1D~geometries with ultra-cold
atoms trapped along or within an optical nanofiber. Broadband radiation force
interactions might also contribute in astrophysical scenarios as illuminated
cold dust clouds.
