Parity anomaly and spin transmutation in quantum spin Hall
... step is absent [11]. A second experiment reports that the Josephson radiation emitted by a biased junction is also consistent with 4π periodicity [12]. These results are surprising as both experiments were performed without explicitly breaking time-reversal symmetry so that basic theory would predic ...

Effective mass of electron in monolayer graphene: Electron
... Experiments were carried out on the epitaxial graphene grown on (10 10) mm2 nominally on-axis 4H-SiC (0001), Si-face chemo-mechanically polished substrates. All the substrates were obtained from a single 4-in. wafer to avoid the influence of large variations of unintentional off-cut from wafer to ...

On-chip non-reciprocal optical devices based on quantum inspired
... The prediction of such a high degree of isolation elevates the upper limit on the isolator performance. It also indicates that given a suitable mechanism for controlling the garnet films magnetism, one might be able to use the device as a switch to direct input beams to either one of the two output ...

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.
