Abstract
We report results on the dynamics of a moving nematic-isotropic interface. Using thinner samples, the restabilization back to a linear interface at large velocities is observed. This allows a study of the full marginal stability curve, defining a tongue in the relevant parameter space. In this tongue many bifurcations exist. Close to the marginal stability line, sources, sinks, and traveling waves are observed in this system.Keywords
