Abstract
We consider an optically linear fluid containing nanoparticles in which quantum confinement effects permit a controlled saturable absorbance to be exploited. We also incorporate the effects of neighboring particles on the local field that any one particle experiences, when calculating the effective permittivity of that particle close to resonance. Since the particles are free to move, under the influence of the Lorentz force, one can alter their spatial distribution as a function of the local field gradients. The particles will move closer together in regions of high electric field, further increasing the local field in the vicinity of any one of these particles, if their permittivities are higher than that of the host fluid. The particles move apart if the reverse is true.
