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.
