  • Stochastic resonance in a polymer stabilized liquid crystal ferroelectric cell [Elektronski vir]
    Forjan, Matej ...
    We study the impact of static disorder on the phenomenon of stochastic resonance (SR) in a polymer stabilized ferroelectric liquid crystal (PSFLC) cell. This typical soft matter system representative ... forms a basic component in several electrooptic applications. We express the dynamic equations governing the liquid crystal structure and show that the obtained equations have generic form for the SR phenomenon. The polymer network, which is commonly introduced to mechanically stabilize the system, gives rise to a certain degree of static disorder. We show that the random field type disorderhas strongest impact on the SR response. The system of our study can be exploited as a sensitive detector for external coherent signals.
