Spin-flip process
WebMar 11, 2024 · The spin relaxation time is in the order of a few picoseconds, indicating a fast intravalley spin-flip rate. Lastly, the spin-flip rate is found to be independent from electron density in the current range, which can be explained through counteracting spin-flip scattering processes based on electron-electron Coulomb scattering and extrinsic ... Webdependence of the hyperfine-induced spin-flip rate ξ↑↓ (B>0). The red line is a theoretical curve obtained from rate equations by taking into account both photon-assisted hyperfine-induced spin-flip events and spontaneous spin-flip Raman transition.

WebOct 5, 2024 · This interplay of motion is the reason why spin-flip processes in molecules typically take quite long. However, computer simulations have shown that this is not the … WebSpin-flip scattering is a process inside a solid that does not conserve spin, and can therefore switch an incoming spin up state into an outgoing spin down state. Spin dephasing is the process wherein a population of electrons with a common spin state becomes less polarized over time due to different rates of electron spin precession.
Spin-flips are significant astrophysically since a number of physical processes are associated with black hole spins; for instance, jets in active galaxies are believed to be launched parallel to the spin axes of supermassive black holes.
