Nonsingular skyrmions for Landau levels with odd occupation number in a two-dimensional system

  • S. V. Iordanskii
  • S. G. Plyasunov


The number of particles, energy and other physical parameters in the presence of a skyrmion vortex have been calculated using the gradient expansion technique. Unlike other researchers, we have not used the approximation of functions projected on a single Landau level. If other Landau levels are included in the scheme, we have a simple physical model and a substantially modified expression for the skyrmion energy. Generation of one skyrmion is thermodynamically favorable, so they should emerge spontaneously near odd-integer filling factors.
