Abstract:
We report on a study of the quasielectron-quasihole and skyrmion-antiskyrmion bound states in the ν=1 quantum Hall regime. The short range attraction potential is assumed to be determined by a point magnetic impurity. The calculations are performed within the strong field approximation when the binding energy and the characteristic electron-electron interaction energy are smaller than the Landau level spacing. The Excitonic Representation technique is used in that case.
