Title: FRONT PROPAGATION INTO UNSTABLE AND METASTABLE STATES IN LIQUID-CRYSTALS - LINEAR AND NONLINEAR MARGINAL-STABILITY ANALYSIS
Abstract: We discuss the front propagation in ferroelectric chiral smectic liquid (Sm-C*}) subjected to electric: and magnetic fields that are parallel to smectic layers. The reversal of the electric field the motion of domain walls or fronts that propagate into either unstable or a metastable state. In both regimes,the front velocity is exactly. Depending on the field, the speed of a front into the unstable state is given either by the so-called marginal-stability velocity of by the nonlinear expression. The crossover between these two regimes be tuned by a magnetic field. The influence of initial conditions on velocity selection problem can also be studied in such experiments. therefore offers a unique opportunity to study different aspects of front propagation in an experimental system.
