Photonic spin Hall effect: fundamentals and emergent applications
WebApr 1, 2006 · The spin Hall effect is the antisymmetric spin accumulation in a finite width system driven by an applied electric field. • The word intrinsic is reserved for the intrinsic contribution to the spin-current generated in the absence of scattering. WebNov 7, 2016 · The spin Hall effect (SHE) does not require the presence of a magnetic field, in fact a B → field orthogonal to the spin polarisation direction will remove the effect. Coupling of spin and charge currents Although you ask for a physical (intuitive ) picture, please forgive a little math for reasons of brevity. tema app 2023 keuskupan manado
How does spin Hall effect happen? - Physics Stack …
The spin Hall effect (SHE) is a transport phenomenon predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. It consists of the appearance of spin accumulation on the lateral surfaces of an electric current-carrying sample, the signs of the spin directions being opposite on the opposing boundaries. … See more The spin Hall effect is a transport phenomenon consisting of the appearance of spin accumulation on the lateral surfaces of a sample carrying electric current. The opposing surface boundaries will have spins of … See more The spin Hall effect (direct and inverse) was predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. They also introduced for the first time the notion of spin current. In 1983 Averkiev and Dyakonov proposed a way to measure … See more The spin current is described by a second-rank tensor qij, where the first index refers to the direction of flow, and the second one to the spin component that is flowing. Thus qxy denotes … See more A transformation of spin currents consisting in interchanging (swapping) of the spin and flow directions (qij → qji) was predicted by Lifshits and Dyakonov. Thus a flow in the x … See more Two possible mechanisms give origin to the spin Hall effect, in which an electric current (composed of moving charges) transforms into a spin current (a current of moving spins without charge flow). The original (extrinsic) mechanism devised by Dyakonov and Perel … See more No magnetic field is needed for spin Hall effect. However, if a strong enough magnetic field is applied in the direction perpendicular to the … See more The direct and inverse spin Hall effect can be monitored by optical means. The spin accumulation induces circular polarization of the emitted light, as well as the Faraday (or Kerr) polarization rotation of the transmitted (or reflected) light. Observing the polarization of … See more WebJul 25, 2024 · It can be regarded as an analog of the spin Hall effect in electronic systems: the right-handed and left-handed circular polarization components of light play the role of spin-up and...
