Shot noise induced by nonequilibrium spin accumulation.

Spin-polarized current and shot noise in the presence of spin flip in a quantum dot via nonequilibrium Green's functions

Spin-torque shot noise in magnetic tunnel junctions.

A spin polarized current may transfer angular momentum to a ferromagnet, resulting in a spin-torque phenomenon. At the same time the shot noise, associated with the current, leads to a nonequilibrium stochastic force acting on the ferromagnet. We derive a stochastic version of the Landau-Lifshitz-Gilbert equation for a magnetization of a "free" ferromagnetic layer in contact with a "fixed" ferr...

What can we learn about the dynamics of transported spins by measuring shot noise in spin - orbit - coupled nanostructures ?

We review recent studies of the shot noise of spin-polarized charge currents and pure spin currents in multiterminal semiconductor nanostructures, while focusing on the effects brought by intrinsic Rashba spin-orbit (SO) coupling and/or extrinsic SO scattering off impurities. By generalizing the scattering theory of quantum shot noise to include the full spin-density matrix of electrons injecte...

Nonequilibrium spintronic transport through an artificial Kondo impurity: conductance, magnetoresistance, and shot noise.

We investigate the nonequilibrium transport properties of a quantum dot when spin flip processes compete with the formation of a Kondo resonance in the presence of ferromagnetic leads. Based upon the Anderson Hamiltonian in the strongly interacting limit, we predict a splitting of the differential conductance when the spin flip scattering amplitude is of the order of the Kondo temperature. We d...
