Optical spin hall effect.
A remarkable analogy is established between the well-known spin Hall effect and the polarization dependence of Rayleigh scattering of light in microcavities. This dependence results from the strong spin effect in elastic scattering of exciton polaritons: if the initial polariton state has a zero spin and is characterized by some linear polarization, the scattered polaritons become strongly spin...
متن کاملUniversal intrinsic spin Hall effect.
We describe a new effect in semiconductor spintronics that leads to dissipationless spin currents in paramagnetic spin-orbit coupled systems. We argue that in a high-mobility two-dimensional electron system with substantial Rashba spin-orbit coupling, a spin current that flows perpendicular to the charge current is intrinsic. In the usual case where both spin-orbit split bands are occupied, the...
متن کاملThe Quantum Spin Hall Effect
Most quantum states of condensed matter are classified by the symmetries they break. For example, crystalline solids break translational symmetry, and ferromagnets break rotational symmetry. By contrast, topological states of matter evade traditional symmetrybreaking classification schemes, and they signal the existence of a fundamentally different organizational principle of quantum matter. Th...
متن کاملSpin current, spin accumulation and spin Hall effect.
Nonlocal spin transport in nanostructured devices with ferromagnetic injector (F1) and detector (F2) electrodes connected to a normal conductor (N) is studied. We reveal how the spin transport depends on interface resistance, electrode resistance, spin polarization and spin diffusion length, and obtain the conditions for efficient spin injection, spin accumulation and spin current in the device...
متن کاملSpin quantum Hall effect in unconventional superconductors
We study the properties of the ‘‘spin quantum Hall fluid’’—a spin phase with quantized spin Hall conductance that is potentially realizable in superconducting systems with unconventional pairing symmetry. A simple realization is provided by a dx22y21idxy superconductor which we argue has a dimensionless spin Hall conductance equal to 2. A theory of the edge states of the dx22y21idxy superconduc...
