  • Direct measurement of the g factor of composite fermions 
    Schulze-Wischeler, F.; Mariani, E.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    The activation gap δ of the fractional quantum Hall states was measured as a function of the perpendicular magnetic field. A linear dependence of δ on magnetic field was observed while approaching the spin-polarization ...
  • Interaction-induced spin polarization in quantum dots 
    Rogge, M.C.; Räsänen, E.; Haug, Rolf J. (College Park, MD : American Physical Society, 2010)
    The electronic states of lateral many-electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb-blockade peaks are measured. A ...
