Asymmetric Quantum Shot Noise in Quantum Dots
Hans-Andreas Engel, Daniel Loss
We analyze the frequency-dependent noise of a current through a quantum dot which is coupled to Fermi leads and which is in the Coulomb blockade regime. We show that the asymmetric…
Spin injection across magnetic/non-magnetic interfaces with finite magnetic layers
Alexander Khaetskii, J. Carlos Egues, Daniel Loss +3
We have reconsidered the problem of spin injection across ferromagnet/non-magnetic-semiconductor (FM/NMS) and dilute-magnetic-semiconductor/non-magnetic-semiconductor interfaces, f…
Electron spin dynamics in quantum dots and related nanostructures due to hyperfine interaction with nuclei
John Schliemann, Alexander Khaetskii, Daniel Loss
We review and summarize recent theoretical and experimental work on electron spin dynamics in quantum dots and related nanostructures due to hyperfine interaction with surrounding…
Phonon-induced decay of the electron spin in quantum dots
Vitaly N. Golovach, Alexander Khaetskii, Daniel Loss
We study spin relaxation and decoherence in a GaAs quantum dot due to spin-orbit interaction. We derive an effective Hamiltonian which couples the electron spin to phonons or any o…
Coulomb scattering in a 2D interacting electron gas and production of EPR pairs
D. S. Saraga, B. L. Altshuler, Daniel Loss +1
We propose a setup to generate non-local spin-EPR pairs via pair collisions in a 2D interacting electron gas, based on constructive two-particle interference in the spin singlet ch…
Dissipation effects in spin-Hall transport of electrons and holes
John Schliemann, Daniel Loss
We investigate the spin-Hall effect of both electrons and holes in semiconductors using the Kubo formula in the correct zero-frequency limit taking into account the finite momentum…
