Spin conductance control by electric means: Proposal for an all-electrical spin conductance diode

Electrical probing of the spin conductance of mesoscopic cavities.

We investigate spin-dependent transport in multiterminal mesoscopic cavities with spin-orbit coupling. Focusing on a three-terminal set-up we show how injecting a pure spin current or a polarized current from one terminal generates additional charge current and/or voltage across the two output terminals. When the injected current is a pure spin current, a single measurement allows us to extract...

Conductance spectroscopy of spin-triplet superconductors.

We propose a novel experiment to identify the symmetry of superconductivity on the basis of theoretical results for differential conductance of a normal metal connected to a superconductor. The proximity effect from the superconductor modifies the conductance of the remote current depending remarkably on the pairing symmetry: spin singlet or spin triplet. The clear-cut difference in the conduct...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Spin conductance, dynamic spin stiffness and spin diffusion in itinerant magnets

We discuss analogies between the chargeand spin response functions of itinerant magnets. We show that the spin-analog of the charge stiffness is not given by the usual spin stiffness ρs, but by the dynamic spin stiffness Ds, which is obtained from the dynamic spin conductance Gs(ω) in the limit of vanishing frequency ω. The low-frequency behavior of Gs(ω) is used to define ideal spin conductors...
