Hyperfine-driven persistent currents in mesoscopic rings based on a 2D electron gas with Rashba spin-orbit interaction

Autor: Cherkaskiy, V. A., Shevchenko, S. N., Rozhavsky, A. S., Vagner, I. D.

Publikováno v: Low Temp. Phys. 25, 541 (1999)

We present a detailed theory of induced persistent current produced by hyperfine interaction in mesoscopic rings based on a 2D-electron (hole) gas in the absence of external magnetic field. The persistent current emerges due to combined action of the

Autor: Bezuglyi, E. V., Rozhavsky, A. S., Vagner, I. D., Wyder, P.

Publikováno v: Physical Review B 66, 052508 (2002)

We analyze new spin effects in current-carrying state of superconductor-2D electron gas-superconductor (S-2DEG-S) device with spin-polarized nuclei in 2DEG region. The hyperfine interaction of 2D electrons with nuclear spins, described by the effecti

Electron transport through a mesoscopic metal-CDW-metal junction

Autor: Krive, I. V., Rozhavsky, A. S., Mucciolo, E. R., Oxman, L. E.

In this work we study the transport properties of a finite Peierls-Fr\"ohlich dielectric with a charge density wave of the commensurate type. We show that at low temperatures this problem can be mapped onto a problem of fractional charge transport th

Quasi-one-dimensional charge density wave in electromagnetic field arbitrarily oriented to conducting chains: generalized Frohlich relations

Autor: Rozhavsky, Alexander S., Pershin, Yurij V., Romanovsky, Igor A.

We derive equations for the collective CDW-current transverse conducting chains in a quasi-one-dimensional CDW-conductor. Generalized Frohlich relations between the transverse currents and phase gradients are due to the polarization corrections to th

Is the magnetic field necessary for the Aharonov-Bohm effect in mesoscopics?

Autor: Vagner, I. D., Rozhavsky, A. S., Wyder, P., Zyuzin, A. Yu.

A new class of topological mesoscopic phenomena in absence of external magnetic field (meso-nucleo-spinics)is predicted, which is based on combined action of the nonequilibrium nuclear spin population and charge carriers spin-orbit interaction . As a
