Spin related conductance and polarization via an open ballistic quantum nanoring connected to one input lead and two output ones are studied by considering the Rashba effect based on the transfer matrix method. Our probes show that controlling on Rashba strength leads to 100 percent spin ...
In this paper a method for polarizing protons, antiprotons and ions using the Stern‐Gerlach effect will be discussed. A test of this effect, forseen for t... R Rossmanith - American Institute of Physics 被引量: 2发表: 1988年 Transport theory and spin-transfer physics in d-wave altermagn...
-standing waves can lead four giant lateral Goos-Hanchen shifts as large as the transverse beam width, while the interplay of the two modulated regions can lead difference of resonant angles or energies for the four spin-valley flavors, manifesting an effective spin-valley beam splitting effect. ...
We investigate the interplay between the spin interference and the Fano effect in a three-lead mesoscopic ring with a side-coupled quantum dot (QD). A uniform Rashba spin鈥搊rbit coupling and a perpendicular magnetic field are tuned such that the ring operates as a spin splitter in the ...

Several years ago a selfpolarization effect for stored (anti-)protons and ions was investigated theoretically. The effect is based on the well-known Stern-Gerlach effect in gradient fields. The aim of the ongoing measurements at IUCF is to verify experime ...R. Rossmanith...

During the last years a new polarization effect for protons or antiprotons was investigated theoretically 1,2 . The idea is very simple: a storage ring consists of strong nonlinear fields, the quadrupoles. The nonlinear fields act on the spin of the particle by the Stern-Gerlach effect: the...
Recently, a spin beam splitter, which operates via the GoosHnchen (GH) effect of electrons, was fabricated by depositing ferromagnetic and Schottky metal stripes on top of a semiconductor heterostructure. To explore effective manipulation of its spin polarization of GH shifts, we introduce a ...
