Bound states in a quantized Hall ferromagnet

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.
