Collapses and revivals of spin polarization quantum oscillations in two-dimensional systems of spin 1/2 charged particles with spin-orbit interaction.
We analyzed spin polarization dynamics in a two-dimensional system of spin 1/2 charged particles with spin-orbit interaction in perpendicular magnetic field in the presence of external noise. It was shown that spin polarization reveals quantum oscillations, collapses, and revivals. The hierarchy of time scales corresponding to quantum oscillations, collapses, and revivals was identified and analyzed. It was demonstrated that variation of external magnetic field and noise intensity results in the significant changing of spin fluctuations spectra, which modifies from the triplet structure to the well resolved fine structure.
