NMR linewidth and Skyrmion localization in quantum Hall ferromagnets
A. Villares Ferrer, R. L. Doretto, A. O. Caldeira
The non-monotonic behavior of the NMR signal linewidth in the 2D quantum Hall system is explained in terms of the interplay between skyrmions localization, due to the influence of…

Soliton dynamics in 1D quantum antiferromagnets
A. Villares Ferrer, A. O. Caldeira, A. S. T. Pires
The problem of dissipative motion of solitons in the case of tetramethyl ammonium manganese chloride (TMMC) is studied as a function of the external magnetic field and the temperat…

Skyrmion dynamics in quantum Hall ferromagnets
A. Villares Ferrer, A. O. Caldeira
Exploring a classical solution of the non-linear sigma model for a quantum Hall ferromagnet, a skyrmion-magnon effective hamiltonian is obtained via the collective coordinates meth…
