Fractional Quantum Hall States of Dirac Electrons in Graphene
... Landau levels. Here the special case is m 1, where the dependence of the pseudopotential on the Landau-level index is nonmonotonic; viz., the pseudopotential has the maximum value at n 1. At all of the other m values, the trend is the same as for the nonrelativistic case; i.e., for m 0 the pse ...

Interplay between Classical Magnetic Moments and Superconductivity in Quantum
... helical structure is general, the essential ingredient being the RKKY interaction. Therefore, the same mechanism can apply if the nuclear spins are replaced by classical magnetic moments forming a 1D lattice (not necessarily a regular one), such as magnetic adatoms on top of a metallic surface [14]. ...

... weak rf field is sharp, but the spin resonance is broadened and has a shape Gs (v). One may convince oneself that moving the sharp frequency of the rf field upwards over the broad spin resonance should produce the same results as moving a broad rf field of spectral shape ρ(v) a Gs(v) downwards over ...

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.
