models of liquid crystals in aerogels, Mol. Cryst. Liq. Cryst., 290,
Computer simulation results for spin models and liquid
crystal ordering in aerogels have been compared in order to assess our
understanding of the modeling of these confined systems. The various models
so far adopted are compared with experimental results and with simulation
data for a new Lebwohl-Lasher type model with sprinkled silica spins and
none is found really satisfactory.
