An electron of a given spin in momentum space, while shifting the orthogonal spin in the opposite direction. In the 1990s, the Rashba effect was suggested as a tool for manipulating the spin of electrons in spintronics [10], and realized a few years later in a semiconductor heterostructure, where the spin-orbit interaction was controlled by a.

An important ingredient of the DDT is the spin-orbit coupling of the Rashba [8-10] or Dresselhaus [11,12] types. This Rashba-Dresselhaus (RD) coupling scheme is described by a vector potential which can be made proportional to the spin-1/2 operator of a particle within a plane [13].

We demonstrate clear weak anti-localization (WAL) effect arising from induced Rashba spin-orbit coupling (SOC) in WS 2-covered single-layer and bilayer graphene devices.Contrary to the uncovered region of a shared single-layer graphene flake, WAL in WS 2-covered graphene occurs over a wide range of carrier densities on both electron and hole sides. Ques arise from interfacial spin-orbit coupling but also from the bulk spin Hall effect, and the importance of each contribution is hotly debated [3,19-22]. The correla-tion we ﬁnd opens a way to quantify the contribution from interfacial spin-orbit coupling by measuring the DM inter-action, allowing one to disentangle the two contributions. The Rashba effect, also called Bychkov-Rashba effect, is a momentum-dependent splitting of spin bands in bulk crystals and low-dimensional condensed matter systems (such as heterostructures and surface states) similar to the splitting of particles and anti-particles in the Dirac Hamiltonian. The splitting is a combined effect of spin-orbit interaction and asymmetry of the crystal potential.

PDF Generalized Rashba-Dresselhaus spin-orbit coupling for cold atoms.

. Spin-orbit coupling (SOC), particularly Rashba spin-orbit coupling (RSOC), plays a key role in the well-known Hall effect [5, 6]. The Rashba-type effective interracial spin-orbit Hamiltonian was offered by E. I. Rashba to investigate the influence of asymmetric interfaces in 2DEG. Breaking the structure inversion symmetry, such as. 2.2. Spin current in the Rashba spin orbital coupling model Let us now consider the particular case of the Rashba Hamiltonian in an external electric eld. The time dependent Rashba Hamiltonian is given by HR(t) = P(t)2 2m + (Px(t)Sy Py(t)Sx): (11) For a given P(t), the instantaneous eigenstates are given by j ;P(t)i = URj i; (12).

We theoretically propose that Rashba-type band splitting can be achieved in binary alloyed hexagonal PX nanosheets (X = As, Sb, and Bi). The lack of inversion symmetry results in an effective electric field perpendicular to the basal plane of PX, hence, leading to Rashba-type spin-orbit coupling (SOC) in the. We report on a two-dimensional (2D) V1-xPtxSe2 alloy that exhibits ferromagnetic order and Rashba spin-orbit coupling. Although ferromagnetism is absent in 1T-VSe2 because of the competition with the charge density wave phase, we demonstrate theoretically and experimentally that the substitution of vanadium by platinum in VSe2 (10-50%) to form a homogeneous 2D alloy restores. The strong spin-orbit coupling in BiTeX has a significant influence on the graphene Dirac states, resulting in the topologically nontrivial band structure, which is confirmed by calculated.

Degrees of freedom, forming an effective spin-orbit coupling (SOC). A variety of novel phenomena has been predicted for such systems, for example, the stripe phase and vortex structure in the ground states of spin-orbit-coupled Bose-Einstein condensates (BECs) [15-26], the Rashba pairing bound states (Rashbons) [27,28] and topological. In these materials, strong intrinsic spin-orbit coupling (SOC) stemming from the heavy metal atoms in the inorganic framework (i.e., Pb or Sn) plays a decisive role in significantly lowering the. Manipulating the electron spin with the aid of spin-orbit coupling (SOC) is an indispensable element of spintronics. Electrostatically gating a material with strong SOC results in an effective magnetic field which can in turn be used to govern the electron spin. In this work, we report the existence and electrostatic tunability of Rashba SOC in multilayer InSe.

The Rashba and Dresselhaus types of spin-orbit coupling are two typical linear coupling forms. We establish the fundamental physics of a model which can be viewed as the double version of the Rashba and Dresselhaus spin-orbit coupling. This model describes the low energy physics of a class of massless Dirac fermions in spin-orbit systems.

Here, we report observations of pronounced ZBCPs in hybrid junctions composed of an oxide heterostructure LaAlO 3 / SrTiO 3 and an elemental superconductor Nb, where the two-dimensional electron system (2DES) at the LaAlO 3 / SrTiO 3 interface is known to accommodate gate-tunable Rashba spin-orbit coupling (SOC). Remarkably, the ZBCPs exhibit a. A giant Rashba-like spin splitting has recently been discovered for bulk conduction and valence band states of bismuth tellurohalide semiconductors (13-15).Arising because of a combination of bulk inversion asymmetry (), strong atomic spin-orbit coupling, and a negative crystal field splitting of the valence bands (), Rashba parameters have been uncovered that are among the highest of any. Rashba spin splitting (RSS) in biased semiconductor quantum wells is investigated theoretically based on eight-band k center dot p theory. We find that at large wave vectors, RSS is both nonmonotonic and anisotropic as a function of in-plane wave vector, in contrast to the widely used isotropic linear model. We derive an analytical expression for RSS, which can qualitatively reproduce such.
