“…The excitation time obtained here, for the electron-hole mass-vortex at , is of the order of the decoupling time of the vertically-stacked pair of spin-vortices with core-core bound states, predicted theoretically in previous studies [52,53] and observed experimentally in a recent study [54]. Another physical observation concerns the construction of the electron band mass-vortex presented in Figures 1 and 7.…”

The present report provides a phenomenological theory for monolayer graphene, in which two worlds, the quantum and the classical, meet and complete each other in the most natural manner. In the present report, electron mass-vortex representation is introduced, and the surface tension excitation states in the monolayer graphene are defined. The bandmass of the electrons at the Dirac's point was calculated through the mathematical introduction of a mass-dispersion relation. As a consequence, the Dirac's energy dispersion in monolayer graphene from classical Newton's law was obtained. Within the scope of the semiclassical theory, it was demonstrated that there was the presence of surface spin tension vectorial field, which, possibly, closely links the surface tension and the spin tension states of the helical surface. The surface tension associated with the confinement of the electron band mass-vortex at the Dirac's point was calculated, and the relaxation time of the surface tension state was predicted with accuracy. Moreover, it was demonstrated, phenomenologically, that the manifolds on S (6) are not integrable (which had been a longstanding problem in the group theory). The principal reason for this was attributed to the irreducibility of the spinorial group Spin(6) R at the Dirac's point, because of band-mass formation and confinement via the gravitational field.

“…Свойства вихревого СТНО, когда магнитный вихрь существует в каждом из магнитных слоев [8][9][10][11][12][13][14], в значительной степени зависят от полярности вихрей. Теоретически показано, что с помощью спин-поляризованного тока можно возбудить гиротропные колебания магнитостатически связанных вихрей с постоянной частотой, которая может меняться при приложении магнитного поля [12,13].…”

The combined influence of a spin polarized current and an external magnetic field for switching the polarity of vortices in spin-transfer nanooscillators 400 nm in diameter is studied. A diagram is constructed of the dependence of the magnitude of the spin-polarized current on the magnitude of the magnetic field, which separately switches the polarity of the vortex in the magnetic layers of the spin-transfer nanooscillator.

“…The properties of a vortex STNO, when the magnetic vortex exists in each of the magnetic layers [8][9][10][11][12][13][14], largely depend on the polarity of the vortices. It is theoretically shown that with the help of a spin-polarized current it is possible to excite gyrotropic oscillations of magnetostatically coupled vortices with a constant frequency, which can change when the magnetic field is applied [12,13].…”
