Spin currents and spin superfluidity
The present review analyzes and compares various types of dissipationless spin transport: (1) Superfluid transport, when the spin-current state is a metastable state (a local but not the absolute minimum in the parameter space). (2) Ballistic spin transport, when spin is transported without losses simply because sources of dissipation are very weak. (3) Equilibrium spin currents, i.e., genuine ...
متن کاملSpintronics: Taming spin currents.
T aking advantage of the fact that electrons, photons and some elementary excitations have an intrinsic angular momentum (spin) offers a fascinating opportunity to study materials properties. Introducing a net imbalance between spins pointing in different directions (say, 'up' and 'down') is one way to probe phenomena including spin–orbit and hyperfine coupling, pairing of unconventional superc...
متن کاملSpin susceptibilities, spin densities, and their connection to spin currents
We calculate the frequency-dependent spin susceptibilities for a two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit interactions. The resonances of the susceptibilities depend on the relative values of the Rashba and Dresselhaus spin-orbit constants, which could be manipulated by gate voltages. We derive exact continuity equations, with source terms, for the spin density a...

متن کاملSpin-to-charge conversion of mesoscopic spin currents.
Recent theoretical investigations have shown that spin currents can be generated by passing electric currents through spin-orbit coupled mesoscopic systems. Measuring these spin currents has, however, not been achieved to date. We show how mesoscopic spin currents in lateral heterostructures can be measured with a single-channel voltage probe. In the presence of a spin current, the charge curre...
