Spontaneous Spin-Polarization of Ballistic Electrons in Single Mode Quantum Wires due to Spin-Splitting

We show that a quantum wire device with spin splitting can work as an active spin polarizer. Hot electrons in one ‘spin’ subband (e.g. ‘spin-up’) may pass such a device with weak electron pair scattering, while electrons in the opposite subband (‘spindown’) may have high conversion probability into the ‘spin-up’ subband, resulting in spin polarization of a hot electron beam. Under different cir...

Rotation intrinsic spin coupling—the parallelism description

For the Dirac particle in the rotational system, the rotation induced inertia effect is analogously treated as the modification of the “spin connection” on the Dirac equation in the flat spacetime, which is determined by the equivalent tetrad. From the point of view of parallelism description of spacetime, the obtained torsion axial-vector is just the rotational angular velocity, which is inclu...

On the Spin-rotation-gravity Coupling

The inertial and gravitational properties of intrinsic spin are discussed and some of the recent work in this area is briefly reviewed. The extension of relativistic wave equations to accelerated systems and gravitational fields is critically examined. A nonlocal theory of accelerated observers is presented and its predictions are compared with observation.

Observable frequency shifts via spin-rotation coupling

The phase perturbation arising from spin-rotation coupling is developed as a natural extension of the celebrated Sagnac effect. Experimental evidence in support of this phase shift, however, has yet to be realized due to the exceptional sensitivity required. We draw attention to the relevance of a series of experiments establishing that circularly polarized light, upon passing through a rotatin...
