Persistent spin current in anisotropic spin ring
The persistent spin current in an anisotropic spin ring penetrated by a SU(2) flux is studied by the Schwinger–Boson mean-field approach. The anisotropy in spin coupling can facilitate the persistent spin current. Ground-state energy and excitation-energy gap are also studied. A peak of spin current occurs at the maximum value of the ground-state energy. r 2006 Published by Elsevier B.V. PACS: ...
متن کاملPersistent spin current in a mesoscopic hybrid ring with spin-orbit coupling.
We investigate the equilibrium property of a mesoscopic ring with a spin-orbit interaction. It is well known that, for a normal mesoscopic ring threaded by a magnetic flux, the electron acquires a Berry phase that induces the persistent (charge) current. Similarly, the spin of an electron acquires a spin Berry phase traversing a ring with a spin-orbit interaction. It is this spin Berry phase th...
متن کاملSpin-current order in anisotropic triangular antiferromagnets.
We analyze instabilities of the collinear up-up-down state of a two-dimensional quantum spin-S spatially anisotropic triangular lattice antiferromagnet in a magnetic field. We find, within the large-S approximation, that near the end point of the plateau, the collinear state becomes unstable due to the condensation of two-magnon bound pairs rather than single magnons. The two-magnon instability...
متن کاملDissipationless spin current in anisotropic p-doped semiconductors
where j j i is the current of the ith component of the spin along the direction j and eijk is the totally antisymmetric tensor in three dimensions (3D). This effect arises because of spinorbit coupling in the valence band of conventional semiconductors such as GaAs and Ge. Sinova et al.3 also found a similar effect in the electron doped conduction band. Transport equation (1) is similar to Ohm’...
متن کاملAnisotropic current-induced spin accumulation in the two-dimensional electron gas with spin-orbit coupling
We investigate the magnetoelectric (or inverse spin-galvanic) effect in the two dimensional electron gases with both Rashba and Dresselhaus spin-orbit coupling using an exact solution of the Boltzmann equation for electron spin and momentum. The spin response to an in-plane electric field turns out to be highly anisotropic while the usual charge conductivity remains isotropic, contrary to earli...
