We study analytically and numerically the ratchet transport of interacting particles induced by a monochromatic driving in asymmetric two-dimensional structures. The ratchet flow is preserved in the limit of strong interactions and can become even stronger compared to the noninteracting case. The developed kinetic theory gives a good description of these(More)
We develop a theoretic description of the photogalvanic current induced by a high frequency radiation in asymmetric nanostructures and show that it describes well the results of numerical simulations. Our studies allow to understand the origin of the electronic ratchet transport in such systems and show that they can be used for creation of new types of(More)
The magnetic field, applied to a size-quantized system produces equilibrium persistent current non-uniformly distributed across the system. The distributions of dia-and para-magnetic currents and magnetic field in a quantum well is found. We discuss the possibility of observation of field distribution by means of NMR. Traditionally, the magnetic field,(More)
Inelastic light scattering by electrons of a two-dimensional system taking into account the Rashba spin-orbit interaction (SOI) in the conduction band is theoretically investigated. The case of resonance scattering (frequencies of incident and scattered light are close to the effective distance between conduction and spin-split-off bands of the AIIIBV-type(More)
We have discovered an unexpected and surprising fact: a 2D axially symmetric short-range potential contains an infinite number of the levels of negative energy if one takes into account the spin-orbit (SO) interaction. For a shallow well (meU0R2/h2<<1, where me is the effective mass and U0 and R are the depth and the radius of the well, respectively) and(More)
Light absorption due to transitions between the edge and two-dimensional (2D) states of a 2D topological insulator (TI) is considered in the Volkov-Pankratov model. It is shown that the transitions are allowed only for the in-plane electric field orthogonal to the TI edge. It is found that the absorption is accompanied by pure spin photocurrent along the TI(More)
