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…
Variable resistance at the boundary between semimetal and excitonic insulator
Massimo Rontani, L. J. Sham
We solve the two-band model for the transport across a junction between a semimetal and an excitonic insulator. We analyze the current in terms of two competing terms associated wi…
Coherent transport in homojunction between excitonic insulator and semimetal
Massimo Rontani, L. J. Sham
From the solution of a two-band model, we predict that the thermal and electrical transport across the junction of a semimetal and an excitonic insulator will exhibit high resistan…
Stimulated and spontaneous optical generation of electron spin coherence in charged GaAs quantum dots
M. V. Gurudev Dutt, Jun Cheng, Bo Li +9
We report on the coherent optical excitation of electron spin polarization in the ground state of charged GaAs quantum dots via an intermediate charged exciton (trion) state. Coher…
Ultrafast initialization and QND-readout of a spin qubit via control of nanodot-vacuum coupling
Ren-Bao Liu, Wang Yao, L. J. Sham
Ultrafast initialization enables fault-tolerant processing of quantum information while QND readout enables scalable quantum computation. By spatially assembling photon resonators…
Theory of Spin Orientation of Semiconductor Carriers at a Ferromagnetic Interface
J. P. McGuire, C. Ciuti, L. J. Sham
A quantum theory of the spin-dependent scattering of semiconductor electrons by a Schottky barrier at an interface with a ferromagnet is presented. The reflection of unpolarized no…
