Title: Skyrmion dynamics in quantum Hall ferromagnets
Author: Ferrer, AV
Caldeira, AO
Abstract: Exploring a classical solution of the nonlinear sigma model for a quantum Hall ferromagnet, a Skyrmion-magnon effective Hamiltonian is obtained via the collective coordinates method. Using the Feynman-Vernon functional-integral formalism for this model we find the temperature-dependent transport coefficients which characterize a single Skyrmion dynamics.
