Shot noise and spin-orbit coherent control of entangled and spin polarized electrons
We extend our previous work on shot noise for entangled and spin polarized electrons in a beamsplitter geometry with spin-orbit (s-o) interaction in one of the incoming leads (lead 1). Besides accounting for both the Dresselhaus and the Rashba spin-orbit terms, we present general formulas for the shot noise of singlet and triplets states derived within the scattering approach. We determine the ...
متن کاملRashba spin-orbit interaction and shot noise for spin-polarized and entangled electrons.
We study shot noise for spin-polarized currents and entangled electron pairs in a four-probe (beam-splitter) geometry with a local Rashba spin-orbit (s-o) interaction in the incoming leads. Within the scattering formalism we find that shot noise exhibits Rashba-induced oscillations with continuous bunching and antibunching. We show that entangled states and triplet states can be identified via ...
متن کاملnoise for entangled and spin - polarized electrons
We review our recent contributions on shot noise for entangled electrons and spin-polarized currents in novel mesoscopic geometries. We first discuss some of our recent proposals for electron entanglers involving a superconductor coupled to a double dot in the Coulomb blockade regime, a superconductor tunnel-coupled to Luttinger-liquid leads, and a triple-dot setup coupled to Fermi leads. We br...
متن کاملSpin-Polarized Electrons
In numerous experiments involving electrons, the ability to manipulate the spin of the electron gives unique additional information. For many years, however, such experiments were extraordinarily rare because of the absence of a good source of spin-polarized electrons. Up to the time this paper appeared, sources of spin-polarized electrons produced electron beams of very low intensity or polari...
متن کاملPhotoemfssion of spin - polarized electrons from GaAs
The spin polarization of electrons photoemitted from (110) GaAs by irradiating with circularly polarized light of energy 1.5 & heu & 3.6 eU was measured by Mott scattering. The GaAs surface was treated with cesium and oxygen to obtain a negative electron af6nity (NEA), The spectrum of spin polarization P(hem) exhibits a peak (P = 40%) at threshold arising from transitions at I, and positive (P ...
