COULOMB EFFECTS ON THE SPIN POLARIZATION OF QUANTUM RINGS
Annotation
We consider electrons in a circular nanoring of zero width, in magnetic field, and with Rashba spin-orbit interaction. We include the Coulomb interaction in the the ”exact diagonalization” manner. The Coulomb interaction has strong effects on the spin polarization which may be totally different than for noninteracting electrons. Our current results include up to four electrons, but this number can easily be increased.
