Phys. Rev. Lett. 83, 4057–4060 (1999)Two-Scale Competition in Phase Separation with ShearReceived 15 April 1999; published in the issue dated 15 November 1999 The behavior of a phase separating binary mixture in uniform shear flow is investigated by numerical simulations and in a renormalization group approach. Results show the simultaneous existence of domains of two characteristic scales. Stretching and cooperative ruptures of the network produce a rich interplay where the recurrent prevalence of thick and thin domains determines log-time periodic oscillations. A power-law growth R(t)∼tα of the average domain size, with α = 4/3 and α = 1/3 in the flow and shear direction, respectively, is shown to be obeyed. © 1999 The American Physical Society URL:
