Borunda, M. F.; Liu, Xin; Kovalev, Alexey A.; Liu, Xiong-Jun; Jungwirth, T.; Sinova, Jairo. (American Physical Society, 2008)We study the quantum interference effects induced by the Aharonov-Casher phase in asymmetrically confined two-dimensional electron and heavy-hole ring structure systems, taking into account the electrically tunable spin-orbit ...

Kovalev, Alexey A.; Borunda, M. F.; Jungwirth, T.; Molenkamp, L. W.; Sinova, Jairo. (American Physical Society, 2007)We study the quantum interference effects induced by the Aharonov-Casher phase in a ring structure in a two-dimensional heavy-hole (HH) system with spin-orbit interaction realizable in narrow asymmetric quantum wells. The ...

Sinitsyn, N. A.; MacDonald, A. H.; Jungwirth, T.; Dugaev, V. K.; Sinova, Jairo. (American Physical Society, 2007)The anomalous Hall effect (AHE) is a consequence of spin-orbit coupling in a ferromagnetic metal and related primarily to density-matrix response to an electric field that is off-diagonal in band index. For this reason ...

Nunner, Tamara S.; Sinitsyn, N. A.; Borunda, Mario F.; Dugaev, V. K.; Kovalev, A. A.; Abanov, Artem; Timm, Carsten; Jungwirth, T.; Inoue, Jun-ichiro; MacDonald, A. H.; Sinova, Jairo. (American Physical Society, 2007)The anomalous Hall effect in a magnetic two-dimensional electron gas with Rashba spin-orbit coupling is studied within the Kubo-Streda formalism in the presence of pointlike potential impurities. We find that all contributions ...

Hankiewicz, EM; Li, J.; Jungwirth, T.; Niu, Q.; Shen, SQ; Sinova, Jairo. (American Physical Society, 2005)We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron and hole finite size mesoscopic systems. The ...

Liu, Xin; Borunda, M. F.; Liu, Xiong-Jun; Sinova, Jairo. (American Physical Society, 2009)We study the interference effect induced by the Aharonov-Casher phase on the Josephson current through a semiconducting ring attached to superconducting leads. Using a one-dimensional model that incorporates spin-orbit ...

Kovalev, Alexey A.; Vyborny, Karel; Sinova, Jairo. (American Physical Society, 2008)We present the analytical description of the anomalous Hall effect (AHE) in a two-dimensional electron gas (2DEG) ferromagnet within the Keldysh formalism. These results unify the three linear-response approaches to AHE ...

Hankiewicz, EM; Molenkamp, LW; Jungwirth, T.; Sinova, Jairo. (American Physical Society, 2004)We study theoretically the manifestation of the spin Hall effect in a two-dimensional electronic system with Rashba spin-orbit coupling via dc-transport measurements in realistic mesoscopic H-shape structures. The ...

Hankiewicz, EM; Jungwirth, T.; Dietl, T.; Timm, C.; Sinova, Jairo. (American Physical Society, 2004)We report on a study of the ac conductivity and magneto-optical properties of metallic ferromagnetic (III, Mn)V semiconductors in the infrared to visible spectrum at zero temperature. Our analysis is based on the successful ...
-
Sherman, EY; Sinova, Jairo. (American Physical Society, 2005)We investigate the spin dynamics and relaxation in remotely doped two dimensional electron systems where the dopants lead to random fluctuations of the Rashba spin-orbit coupling. Due to the resulting random-spin precession, ...

Liu, Xin; Liu, Xiong-Jun; Sinova, Jairo. (American Physical Society, 2011)We study the spin dynamics in a high-mobility two-dimensional electron gas with generic spin-orbit interactions (SOI's). We derive a set of spin-dynamics equations that capture purely exponentially the damped oscillatory ...

Sinitsyn, NA; Hankiewicz, EM; Teizer, Winfried; Sinova, Jairo. (American Physical Society, 2004)We investigate the spin-current linear response conductivity tensor to an electric field in a paramagnetic two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit coupling in the weak scattering regime ...

Kovalev, Alexey A.; Tserkovnyak, Yaroslav; Vyborny, Karel; Sinova, Jairo. (American Physical Society, 2009)We present a study of transport in multiple-band noninteracting Fermi metallic systems based on the Keldysh formalism and the self-consistent T-matrix approximation (TMA) taking into account the effects of Berry curvature ...
