Selective optical manipulation of the spin state of a single magnetic impurity in a semiconductor quantum dot (2004)

Govorov, A. O., Kalameitsev, A. V.

We consider the optical properties of a single magnetic impurity in a self-assembled quantum dot. We show that using the resonant pumping one can address and manipulate selectively individual spin...

Spin-dependent transport of electrons in the presence of smooth lateral barrier and spin-orbit interaction (2004)

Govorov, A. O., Kalameitsev, A. V., Dulka, J. P.

We describe theoretically the process of multi-beam reflection in a two-dimensional electron system with a lateral potential barrier. Due to spin-orbital interaction, the reflection process leads to...

Kondo-excitons and Auger processes in self-assembled quantum dots (2003)

Govorov, A. O., Karrai, K., Warburton, R. J., Kalameitsev, A. V.

We describe theoretically novel excitons in self-assembled quantum dots interacting with a two-dimensional electron gas in the wetting layer. In the presence of the Fermi sea, the optical lines...

Magneto-optical properties of charged excitons in quantum dots (2002)

Govorov, A. O., Schulhauser, C., Haft, D., Kalameitsev, A. V., Chaplik, A., Warburton, R. J., ...

We present both experimental and theoretical results on the influence of a magnetic field on excitons in semiconductor quantum dots. We find a pronounced difference between the strong and weak...

Magnetoexcitons in quantum-ring structures: a novel magnetic interference effect (2001)

Ulloa, S. E., Govorov, A. O., Kalameitsev, A. V., Warburton, R., Karrai, K.

A novel magnetic interference effect is proposed for a neutral, but polarizable exciton in a quantum ring with a finite width. The magnetic interference effect originates from the nonzero dipole...

Excitons in quantum-ring structures in a magnetic field: Optical properties and persistent currents (2001)

Govorov, A. O., Kalameitsev, A. V., Warburton, R., Karrai, K., Ulloa, S. E.

We study theoretically the magnetic field effect on a neutral, but polarizable exciton confined in quantum-ring structures. For excitons with a nonzero dipole moment, a novel magnetic interference...

Quantum wires and dots driven by intense surface acoustic waves and the quantum attenuation of sound in an electron plasma (2001)

Govorov, A. O., Kalameitsev, A. V., Kovalev, V. M.

We develop a quantum theory of the nonlinear interaction between intense surface acoustic waves and electrons of a quantum well in the regime of moving quantum wires and dots. The quantum nonlinear...

Govorov, A. O., Kalameitsev, A. V., Kovalev, V. M., Wixforth, A.

Nonlinear acousto-electric transport in a two-dimensional electron system (2000)

Govorov, A. O., Kalameitsev, A. V., Rotter, M., Wixforth, A., Kotthaus, J. P., Hoffmann, K. H., ...

We study both theoretically and experimentally the nonlinear interaction between an intense surface acoustic wave and a two-dimensional electron plasma in semiconductor-piezocrystal hybrid...
