PDF Supersolid with nontrivial topological spin textures in spin-orbit.

In a ferromagnetic metal layer, the coupled charge and spin diﬀusion equations are obtained in the presence of both Rashba spin-orbit interaction and magnetism. The misalignment between the magnetization and the nonequilibrium spin density induced by the Rashba ﬁeld gives rise to Rashba spin torque acting on the ferromagnetic order parameter. Results are summarized in Fig. 1. For small Rashba coupling, we ﬁnd the TI (at small onsite interaction U) and XY-AFM phases (at large interactions U) which are also present in the Kane-Mele-Hubbard model without the Rashba coupling. Larger Rashba coupling induces a topologically nontrivial direct-gap-only semiconductor before the system.

Rashba effect - Wikipedia.

Spin-orbit coupling effect in structures with broken inversion symmetry, known as the Rashba effect, facilitates spin-orbit torques (SOTs) in heavy metal/ferromagnet/oxide structures, along with the spin Hall effect. Electric-field control of the Rashba effect is established for semiconductor interfaces, but it is challenging in structures involving metals owing to the screening effect. This has now been corrected in the online PDF; the HTML version was unaffected. References. Born,... Rashba, E. I. Spin-orbit coupling and spin transport. Phys. E 34, 31–35 (2006).

Rashba-type spin-orbit coupling in bilayer Bose-Einstein.

The Rashba spin–orbit cou- pling produces spin flipping in the conductivity. The spin flipping occurs at sharp resonance peaks. This sharp anomaly at the edges of the conductance plateaus is behind the sudden increase of the spin-flip phenomenon.43,44 BY increasing the Fig. 3. Magnetization Dynamics in Pt/Ni80Fe20 Nanowires Induced by Spin Hall Effect Liu Yang 2015 Spin current is the flow of electron spin angular momentum. It can either be partially spin polarized current generated due to the exchange interactions of spins and local magnetization, or pure spin current generated from spin orbit interaction. The two-dimensional Rashba-Hubbard model is investigated in order to clarify the electron correlation effects in non-centrosymmetric metals. The renormalization effect on Rashba spin-orbit coupling (RSOC) is calculated on the basis of second-order and third-order perturbation theories. We show that RSOC is enhanced by the electron correlation. On the other hand, the spin-splitting of the Fermi.

Gate-Tunable Spin-Orbit Coupling in a Germanium Hole Double Quantum Dot.

The spin-orbit coupling strength can be controlled in a ﬁeld effect transistor setup. This provides a variety of systems in which the effect can be observed. Finally, we stress that the effect is not limited to Rashba spin-orbit coupling sys-tems. It is similarly expected to manifest in the presence of Dresselhaus or bulk spin-orbit interaction. Spin-orbit (SO) coupling is essential for realizing topo-logical insulators, noninteracting fermionic systems with topological order [1,2], and yet in other contexts it leads to parasitic effects such as reduced spin coherence times [3]. As with the progression from the single-particle integer quantum.

PDF Inﬂuence of Rashba spin-orbit coupling on the Kondo effect.

Idea of manipulating spin states to create new, spin-based electronic devices [1,2]. Rashba spin-orbit (SO) coupling [3] has been proposed as a mechanism for spin control, not only because of the possibility of its external manipulation, but also because it is the physical origin of spin-dependent phenomena such as anisotropic magnetoresistance. The spin–orbit coupling is the interaction between the electron’s spin and its orbital motion around the nucleus. When an electron moves in the finite electric field of the nucleus, the spin–orbit coupling causes a shift in the electron’s atomic energy levels due to the electromagnetic interaction between the spin of the electron and the electric field.

On the Role of Rashba Spin-Orbit Coupling in Graphene Nanoribbons.

Oct 27, 2014 · Spin-orbit (SO) coupling is the crucial parameter to drive topological-insulating phases in electronic band models. In particular, the generic emergence of SO coupling involves the Rashba term which fully breaks the SU(2) spin symmetry. As soon as interactions are taken into account, however, many theoretical studies have to content themselves with the analysis of a simplified U(1)-conserving. Pendicular to the interface plane. The spin-orbit coupling, that is { in a nonrelativistic formulation { proportional to the gradient of the potential, results in Rashba spin-orbit coupling and consequently in polarized electronic states in a two-dimensional electron gas (2DEG) con ned to the band-bending region.
