... of the degeneracy of the spin components of a spin-orbit free (SOF) state in the absence of an external magnetic field. This picture of ZFS is based on the separation of SOF and spin-dependent effects such as spin-orbit coupling (SOC). With this viewpoint, ZFS between the spin components of S > 1=2 ...

In turn, the coupling to the solid-state environment (e.g., phonons) is strongly suppressed and Coulomb correlations among charge carriers are strongly enhanced. Indeed, in the optical spectra o ...

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.
