Abstract
Recent experiments have shown that a quantized Hall plateau can occur in double layer systems at total filling factor v=1/2, though there is no plateau at v=1/2 in a normal single layer system. For the single layer system, considerable insight has been provided by a theory based on the fermion Chern-Simons picture, where the electrons are transformed into fermions that carry two flux quanta of a Chern-Simons gauge field. A similar picture can be used to characterize ground states which have been proposed for the two layer system.
