Massive skyrmions in quantum Hall ferromagnets
arXiv:cond-mat/0005195 · doi:10.1103/PhysRevB.63.075315
Abstract
We apply the theory of elasticity to study the effects of skyrmion mass on lattice dynamics in quantum Hall systems. We find that massive Skyrme lattices behave like a Wigner crystal in the presence of a uniform perpendicular magnetic field. We make a comparison with the microscopic Hartree-Fock results to characterize the mass of quantum Hall skyrmions at and investigate how the low temperature phase of Skyrme lattices may be affected by the skyrmion mass.
