Quantum Spin Hall Effect [PDF]
Physical Review Letters, 2006 The quantum Hall liquid is a novel state of matter with profound emergent properties such as fractional charge and statistics. Existence of the quantum Hall effect requires breaking of the time reversal symmetry caused by an external magnetic field. In this work, we predict a quantized spin Hall effect in the absence of any magnetic field, where the ...

Challenges in identifying chiral spin textures via the topological Hall effect
Communications Materials, 2022 Hall effect measurements are often used to identify chiral spin textures in materials through the topological Hall effect, but similar Hall signals can arise due to sample inhomogeneity or experimental issues.

Spin Hall effect of excitons [PDF]
Physical Review B, 2008 Spin Hall effect for excitons in alkali halides and in Cu_2O is investigated theoretically. In both systems, the spin Hall effect results from the Berry curvature in k space, which becomes nonzero due to lifting of degeneracies of the exciton states by exchange coupling.

Communications Physics, 2023 Nonequilibrium quantum states can be controlled via the driving field in periodically driven systems. Such control, which is called Floquet engineering, has opened various phenomena, such as the light-induced anomalous Hall effect.

Voltage-driven gigahertz frequency tuning of spin Hall nano-oscillators
Nature Communications, 2022 Spin-hall nano-oscillators are a variation on spin-torque nano-oscillators, where the spin-Hall effect is used to drive oscillations, however past examples have had limited frequency tunability.

Spin Hall effect, Hall effect, and spin precession in diffusive normal metals [PDF]
Physical Review B, 2005 We study transport in normal metals in an external magnetic field. This system exhibits an interplay between a transverse spin imbalance (spin Hall effect) caused by the spin-orbit interaction, a Hall effect via the Lorentz force, and spin precession due to the Zeeman effect. Diffusion equations for spin and charge flow are derived. The spin and charge

Spin current, spin accumulation and spin Hall effect [PDF]
Science and Technology of Advanced Materials, 2008 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 ...

Negative spin Hall magnetoresistance of normal metal/ferromagnet bilayers
Nature Communications, 2020 In normal metal/ferromagnet bilayers, the spin Hall magnetoresistance originating from the spin Hall effect of normal metal possesses positive sign regardless of the sign of spin Hall conductivity of normal metal.

Enhanced Spin Hall Shift by Multipoles of Different Orders in Spherical Particles
Photonics, 2023 The spin–orbit interaction of light is universal in the process of light scattering, and an important aspect is the spin Hall effect. The spin Hall effect of light also exists in a three-dimensional (3D) system.
