Skyrmions in quantum Hall ferromagnets as spin-waves bound to unbalanced magnetic flux quanta
J. H. Oaknin, B. Paredes, C. Tejedor
A microscopic description of (baby)skyrmions in quantum Hall ferromagnets is derived from a scattering theory of collective (neutral) spin modes by a bare quasiparticle. We start b…

Skyrmions and edge spin excitations in quantum Hall droplets
J. H. Oaknin, L. Martin-Moreno, C. Tejedor
We present an analysis of spin-textures in Quantum Hall droplets, for filling factors . Analytical wavefunctions with well defined quantum numbers are given for the low-…

Low-lying excitations of Quantum Hall Droplets
J. H. Oaknin, L. Martin-Moreno, J. J. Palacios +1
We present the adequate circular representation of charge density excitations in Quantum Hall droplets at filling factor 1. A novel set of operators describes magnetoexcitons with…
