dc.descriptionIn this paper, I study the topological excitations in a pairing state in double layer systems at Landau level filling factor $ν=1/2$ in the presence of disorders. Due to mismatches between single particle wave functions of composite Fermions in different layers, the sensitivity of the Chern number of the pairing state, with respect to changes of impurities, is infinity. Consequently, Goldstone mode in this pairing state is strongly damped at low temperature. It is argued that this leads to a unique temperature dependence of the drag resistance at low temperature.
