Phys. Rev. Lett. 98, 133601 (2007) [4 pages]Liquid Transport due to Light ScatteringReceived 7 June 2006; published 28 March 2007 Using experiments and theory, we show that light scattering by inhomogeneities in the index of refraction of a fluid can drive a large-scale flow. The experiment uses a near-critical, phase-separated liquid, which experiences large fluctuations in its index of refraction. A laser beam traversing the liquid produces a interface deformation on the scale of the experimental setup and can cause a liquid jet to form. We demonstrate that the deformation is produced by a scattering-induced flow by obtaining good agreements between the measured deformations and those calculated assuming this mechanism. © 2007 The American Physical Society URL:
