Query: Photoinduced electronic and spin properties of two-dimensional electron
  gases with Rashba spin-orbit coupling under perpendicular magnetic fields   We theoretically investigate photoinduced phenomena induced by time-periodic
driving fields in two-dimensional electron gases under perpendicular magnetic
fields with Rashba spin-orbit coupling. Using perturbation theory, we provide
analytical results for the Floquet-Landau energy spectrum appearing due to THz
radiation. By employing the resulting photo-modulated states, we compute the
dynamical evolution of the spin polarization function for an initially prepared
coherent state. We find that the interplay of the magnetic field, Rashba
spin-orbit interaction and THz radiation can lead to inversion of the spin
polarization. The dynamics also induces fractional revivals and non-trivial
beating patterns in the autocorrelation function due to interference of the
photo-modulated quantum states. We also calculate the transverse photo-assisted
conductivity in the linear response regime using Kubo formalism and analyze the
impact of the radiation field and Rashba spin-orbit interaction. In the static
limit, we find that our results reduce to well-known expressions of the
conductivity in non-relativistic and quasi-relativistic (topological insulator
surfaces) two-dimensional electron gas thoroughly described in the literature.
We discuss the possible experimental detection of our theoretical prediction
and their relevance for spin-orbit physics at high magnetic fields.
