Query: Systems involving surfactants   Computer simulations of amphiphilic systems are reviewed. Research areas
cover a wide range of length and time scales, and a whole hierarchy of models
and methods has been developed to address them all. They range from
atomistically realistic models, idealized chain models, lattice spin models, to
phenomenological models such as Ginzburg-Landau models and random interface
models. Selected applications are discussed in order to illustrate the use of
the models and the insights they can offer.
