Abstract

We analyze the molecular dynamics heterogeneity of the liquid crystal 4- n -octyl- 4′ -cyanobiphenyl nanoconfined in porous silicon. We show that the temperature dependence of the dynamic correlation length ξwall, which measures the distance over which a memory of the interfacial slowing down of the molecular dynamics persists, is closely related to the growth of the short-range static order arising from quenched random fields. More generally, this result may also shed some light on the connection between static and dynamic heterogeneities in a wide class of condensed and soft matter systems.
