Query: Amplification phenomena of Casimir force fluctuations on close
  scatterers coupled via a coherent fermionic fluid   We study the mechanical actions affecting close scatterers immersed in a
coherent fermionic fluid. Using a scattering field theory, we theoretically
analyse the single-scatterer and the two-scatterer case. Concerning the
single-scatterer case, we find that a net force affects the scatterer dynamics
only in non-equilibrium condition, i.e. imposing the presence of a
non-vanishing particle current flowing through the system. The force
fluctuation (variance) is instead not negligible both in equilibrium and in
non-equilibrium conditions. Concerning the two-scatterer case, an attractive
fluid-mediated Casimir force is experienced by the scatterers at small spatial
separation, while a decaying attractive/repulsive behavior as a function of the
scatterer separation is found. Furthermore, the Casimir force fluctuations
acting on a given scatterer in close vicinity of the other present an
oscillating behavior reaching a long distance limit comparable to the value of
the single-scatterer case. The relevance of these findings is discussed in
connection with fluctuation phenomena in low-dimensional nanostructures and
cold atoms systems.
