Variational study of the ν=1 quantum Hall ferromagnet in the presence of spin-orbit interaction

Schliemann, John ; Egues, J. Carlos ; Loss, Daniel



Abstract

We investigate the ν=1 quantum Hall ferromagnet in the presence of spin-orbit coupling of the Rashba or Dresselhaus type by means of Hartree-Fock-typed variational states. In the presence of Rashba (Dresselhaus) spin-orbit coupling the fully spin-polarized quantum Hall state is always unstable resulting in a reduction of the spin polarization if the product of the particle charge q and the ...
