The voltage probe model is a model of incoherent scattering in quantum transport. Here we use this model to study the effect of spin-flip scattering on electrical conduction through a quantum dot with chaotic dynamics. The spin decay rate $\ensuremath{\gamma}$ is quantified by the correlation of spin-up and spin-down current fluctuations (spin-flip noise). The resulting decoherence reduces the ability of the quantum dot to produce spin-entangled electron-hole pairs. For $\ensuremath{\gamma…

Excess conductance of a spin-filtering quantum dot

The conductance G of a pair of single-channel point contacts in series, one of which is a spin filter, increases from 1/2 to 2/3 x e^2/h with more and more spin-flip scattering. This excess

Effect of inelastic scattering on spin entanglement detection through current noise

We study the effect of inelastic scattering on the spin entanglement detection and discrimination scheme proposed by Egues, Burkard, and Loss [Phys. Rev. Lett. \textbf{89}, 176401 (2002)]. The

Two-electron-entanglement enhancement by an inelastic scattering process

In order to assess inelastic effects on two fermion entanglement production, we address an exactly solvable two-particle scattering problem where the target is an excitable scatterer. Useful

Quantum to classical transition of the charge relaxation resistance of a mesoscopic capacitor

We present an analysis of the effect of dephasing on the single channel charge relaxation resistance of a mesoscopic capacitor in the linear low frequency regime. The capacitor consists of a cavity

Proposal for quantum spin tomography in ferromagnet-normal conductors

We present a theory for a complete reconstruction of nonlocal spin correlations in ferromagnet-normal conductors. This quantum spin tomography is based on cross-correlation measurements of electric

We use a ferromagnetic voltage probe model to study the influence of inelastic scattering on giant magnetoresistance and current-induced torques in ferromagnetic and antiferromagnetic metal spin



Spin detection in quantum dots by electric currents

We develop a theoretical description of transport through quantum dots connected to reservoirs via spin-polarized ballistic contacts. Rate equations account for spin accumulation inside the dot,

Universal Quantum Signatures of Chaos in Ballistic Transport

The conductance of a ballistic quantum dot (having chaotic classical dynamics and being coupled by ballistic point contacts to two electron reservoirs) is computed on the single assumption that its

Phonon-Induced Decay of the Electron Spin in Quantum Dots

We study spin relaxation and decoherence in a GaAs quantum dot due to spin-orbit (SO) interaction. We derive an effective Hamiltonian which couples the electron spin to phonons or any other

Singlet-triplet decoherence due to nuclear spins in a double quantum dot

We have evaluated hyperfine-induced electron spin dynamics for two electrons confined to a double quantum dot. Our quantum solution accounts for decay of a singlet-triplet correlator even in the

Voltage-probe and imaginary-potential models for dephasing in a chaotic quantum dot

We compare two widely used models for dephasing in a chaotic quantum dot: the introduction of a fictitious voltage probe into the scattering matrix and the addition of an imaginary potential to the

Coherent Manipulation of Coupled Electron Spins in Semiconductor Quantum Dots

We demonstrated coherent control of a quantum two-level system based on two-electron spin states in a double quantum dot, allowing state preparation, coherent manipulation, and projective readout.

Shot noise of photon-excited electron-hole pairs in open quantum dots

We investigate shot noise of photon-excited electron-hole pairs in open multiterminal, multichannel chaotic dots. Coulomb interactions in the dot are treated self-consistently giving a

Spin-current shot noise as a probe of interactions in mesoscopic systems.

It is shown that the spin-resolved current shot noise can probe attractive or repulsive interactions in mesoscopic systems, and a setup is proposed in a quantum dot geometry.

Proposal for production and detection of entangled electron-hole pairs in a degenerate electron gas.

We demonstrate theoretically that the shot noise produced by a tunnel barrier in a two-channel conductor violates a Bell inequality. The nonlocality is shown to originate from entangled electron-hole
