Query: Synthesizing variable particle interaction potentials via spectrally
  shaped spatially coherent illumination   Collective scattering of spatially coherent radiation by separated point
emitters induces inter-particle forces. For particles close to nano-photonic
structures as, for example, nano-fibers, hollow core fibers or photonic
waveguides, this pair-interaction induced by monochromatic light is periodic
and virtually of infinite range. Here we show that the shape and range of the
optical interaction potential can be precisely controlled by spectral design of
the incoming illumination. If each particle is only weakly coupled to the
confined guided modes the forces acting within a particle ensemble can be
decomposed to pairwise interactions. These forces can be tailored to almost
arbitrary spatial dependence as they are related to Fourier transforms with
coefficients controlled by the intensities and frequencies of the illuminating
lasers. We demonstrate the versatility of the scheme by highlighting some
examples of unconventional pair potentials. Implementing these interactions in
a chain of trapped quantum particles could be the basis of a versatile quantum
simulator with almost arbitrary all-to-all interaction control.
