Dynamical behavior of a complex fluid near an out-of-equilibrium transition: approaching simple rheological chaos

, 2002
We report here an extensive study of sustained oscillations of the viscosity of a complex fluid near an out-of-equilibrium transition. Using well defined protocols, we perform rheological measurements of the onion texture near a layering transition in a ...
