Quantum Renormalization of the Spin Hall Effect
... current perpendicular to the applied electric field is produced in ferromagnetic metals (AHE), while a spin current rather than a charge current is induced in semiconductors and metals without magnetism (SHE). An extrinsic mechanism of these two effects arises from the skew scattering, i.e., spin-de ...

Chemical Physics High-spin-low-spin transitions in Fe(II) complexes
... Specific properties of transition metal complexes (TMC) are known to be determined by the d-electrons of the transition metal ion. Their low energy excitations are responsible for the absorption bands in the optical spectra and for the magnetic properties. The ground state spin depends on the balanc ...

... dencies on the ring radius become almost horizontal and the levels turn into degenerated with respect to spin orientations. Similar dependencies of the two electron energies on the distance between vertically coupled one-dimensional rings are presented in Fig. 2 for ring radii 1a0 ∗ and 5a0 ∗. One c ...

Nitrogen-vacancy center
The nitrogen-vacancy center (N-V center) is one of numerous point defects in diamond. Its most explored and useful property is photoluminescence, which can be easily detected from an individual N-V center, especially those in the negative charge state (N-V−). Electron spins at N-V centers, localized at atomic scales, can be manipulated at room temperature by applying a magnetic field, electric field, microwave radiation or light, or a combination, resulting in sharp resonances in the intensity and wavelength of the photoluminescence. These resonances can be explained in terms of electron spin related phenomena such as quantum entanglement, spin-orbit interaction and Rabi oscillations, and analysed using advanced quantum optics theory. An individual N-V center can be viewed as a basic unit of a quantum computer, and it has potential applications in novel, more efficient fields of electronics and computational science including quantum cryptography and spintronics.
