摘要：
A quantum Hall ferromagnet is considered at integer fillings nu, provided typical Coulomb interaction energy E-c is large compared to the cyclotron energy omega(H). Low-energy collective modes consist of a magnetoplasmon exciton and a gapless spin exciton. All charged excitations have a gap. The activation energy gap for a pair of charged topological excitations-skyrmion and antiskyrmion-is small, i.e., Delta < vomega(H). The electric charge of a skyrmion is the multiple q = evQ, where Q is the integer topological charge. (C) 2002 MAIK "Nauka / Interperiodica".
