When two phase coherent laser beams are crossed at an angle, the electric fields of the beams produce a sinusoidal interference pattern. Partial absorption of the electric fields in a colloidal sample creates a sinusoidal temperature field. The temperature gradient then causes production of concentration gradient in the sample, known as the Ludwig-Soret effect or thermal diffusion. Solutions to nonlinear partial differential equations that describe the effect show that shock waves analogous to fluid shock waves are produced. A mathematical relation between the shock speed and the density...
