    "abstract": "We discuss the front propagation in ferroelectric chiral smectics (SmC*)\nsubjected to electric and magnetic fields applied parallel to smectic layers.\nThe reversal of the electric field induces the motion of domain walls or fronts\nthat propagate into either an unstable or a metastable state. In both regimes,\nthe front velocity is calculated exactly. Depending on the field, the speed of\na front propagating into the unstable state is given either by the so-called\nlinear marginal stability velocity or by the nonlinear marginal stability\nexpression. The cross-over between these two regimes can be tuned by a magnetic\nfield. The influence of initial conditions on the velocity selection problem\ncan also be studied in such experiments. SmC$^*$ therefore offers a unique\nopportunity to study different aspects of front propagation in an experimental\nsystem.",
