Abstract: The research herein studies the Langevin dynamics that allows for an exchange of energy between liquid crystals and the thermal environment. This dynamics leads to fluctuation and dissipation behaviors in the motions of liquid crystals, and therefore drives the system toward non-equilibrium evolutional processes. In particular, for the operations of liquid-crystal metastable systems, the fluctuation could allow an excitation (non-equilibrium) transition against energy barriers to the globally-stable state. Implemented with an actual case of liquid crystal π configuration, this work statistically studies the non-equilibrium metastable transitions and shows the dependence of the transition-time on the correlations (of fluctuations).
