Abstract

The fronts are waves that connect two equilibria. The liquid crystals are no stranger to these phenomena. Front dynamics also was observed in other physical contexts, such as walls separating magnetic domains, fluidized granular states, chemical reactions, solidification, and combustion processes, and population dynamics, to mention a few. We find these phenomena in differents interface dynamics, as part of a robust phenomenon this ranging from chemistry and biology to physics. The propagation and dynamics of fronts depend on the nature of the states that are being connected. The invasion of a state into another is characterized usually by front propagation into unstable states. In the present work, we investigate the anisotropic front propagation close to phase transition SmA-N*. The bifurcation diagram shows a subcritical behavior, and the front speed is according to the mathematical model. A spatiotemporal diagram shows an evolution of the front with preferential direction.”
