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… 


Effects of inversion asymmetry on electron energy band structures in GaSb/InAs/GaSb quantum wells.
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.
Theory of spin-charge-coupled transport in a two-dimensional electron gas with Rashba spin-orbit interactions
We use microscopic linear response theory to derive a set of equations that provide a complete description of coupled spin and charge diffusive transport in a two-dimensional electron gas (2DEG) with
Zero-field satellites of a zero-bias anomaly.
Spin-orbit (SO) splitting, +/-omega(SO), of the electron Fermi surface in two-dimensional systems manifests itself in the interaction-induced corrections to the tunneling density of states,
We study local density of electron states of a two-dimentional conductor with a smooth disorder potential in a non-quantizing magnetic field, which does not cause the standart de Haas-van Alphen
Parametric correlations of local density-of-states fluctuations in disordered pillars, wires and films
We present a theoretical analysis of correlation properties of the local density of states in a disordered emitter probed by resonant tunnelling through a localized impurity state. The emitter is
Exchange-induced enhancement of spin-orbit coupling in two-dimensional electronic systems
We study theoretically the renormalization of the spin-orbit coupling constant of two-dimensional electrons by electron-electron interactions. We demonstrate that, similarly to the $g$ factor, the
Quantum Interference and Electron-Electron Interactions at Strong Spin-Orbit Coupling in Disordered Systems
Transport and thermodynamic properties of disordered conductors are considerably modified when the angle through which the electron spin precesses due to spin-orbit interaction (SOI) during the mean
Level statistics in a two-dimensional system with strong spin-orbit coupling
We study level correlations in a two-dimensional system with a long-range random potential and strong spin-orbit (SO) splitting of the spectrum. The level correlations for sufficiently large

Spectrum of typical fluctuations of local density of states and the NMR line shape in a two-dimensional electronic system.
The Knight-shift distribution function for the two-dimensional weakly disordered metal is determined in the whole temperature region. It has the Gaussian form around the mean value as long as T>T 0 ,
