  • Charge-spin excitations of the Ising-type fractional quantum Hall ferromagnets 
    Výborný, Karel; Dethlefsen, Annelene F.; Haug, Rolf J.; Wójs, Arkadiusz (College Park, MD : American Physical Society, 2009)
    We study the low-lying excitations from the fractional quantum Hall states at filling factors 2/3 and 2/5 and argue that the charge-carrying excitations involve spin flips, and, in particular, possibly more than one. ...
  • Transport gap in a ν=1/3 quantum Hall system: A probe for skyrmions 
    Dethlefsen, Annelene F.; Haug, Rolf J.; Výborný, Karel; Čertík, Ondrej; Wójs, Arkadiusz (College Park, MD : American Physical Society, 2006)
    Transport measurements of the activation gap at fractional filling factor 1/3 are compared to results of exact diagonalization, allowing identification of a small anti-skyrmion as the lowest excitation in the low-field ...
