We study the local density of states (LDOS) of two-dimensional noninteracting electrons in the presence of spin-orbit (SO) coupling. Although SO coupling has no effect on the average density of states, it manifests itself in the correlations of the LDOS. Namely, the correlation function acquires two satellites centered at energy difference equal to the SO splitting, $2{\ensuremath{\omega}}_{\mathrm{SO}}$, of the electron Fermi surface. For a smooth disorder the satellites are well separated…

TLDR
The finite spin splitting at B=0 is dominated by the lack of inversion symmetry in the confining potential well, and the results indicate that the spin splitting increases nonlinearly with the external magnetic field.
