Linking entanglement and quantum phase transitions via density functional theory
L. -A. Wu, M. S. Sarandy, D. A. Lidar +1
Density functional theory (DFT) is shown to provide a novel conceptual and computational framework for entanglement in interacting many-body quantum systems. DFT can, in particular…
Spintronics for electrical measurement of light polarization
H. Dery, L. Cywinski, L. J. Sham
The helicity of a circularly polarized light beam may be determined by the spin direction of photo-excited electrons in a III-V semiconductor. We present a theoretical demonstratio…
Lateral diffusive spin transport in layered structures
H. Dery, L. Cywinski, L. J. Sham
A one dimensional theory of lateral spin-polarized transport is derived from the two dimensional flow in the vertical cross section of a stack of ferromagnetic and paramagnetic lay…
Theory of electron spin decoherence by interacting nuclear spins in a quantum dot
Wang Yao, Ren-Bao Liu, L. J. Sham
We present a quantum solution to the electron spin decoherence by a nuclear pair-correlation method for the electron-nuclear spin dynamics under a strong magnetic field and a tempe…
Theory of Umklapp-assisted recombination of bound excitons in Si:P
Michael N. Leuenberger, L. J. Sham
We present the calculations for the oscillator strength of the recombination of excitons bound to phosphorous donors in silicon. We show that the direct recombination of the bound…
Spin transference and magnetoresistance amplification in a transistor
Hanan Dery, Lukasz Cywinski, Lu J. Sham
A current problem in semiconductor spin-based electronics is the difficulty of experimentally expressing the effect of spin-polarized current in electrical circuit measurements. We…
